In the military avenue, laser can help in target designation and ranging, defensive countermeasures, and so forth. The coming into being of laser virtually adds color to our daily routine in more than one aspect. Even science fictions benefit from it for involving into the stories laser weapons.

When it comes to the field of medicine, the function of laser is even more overwhelming, since it not only facilitates the process of diagnosing and assists the surgeries, but also come as great help for professors in their teaching. It is known to all students who have ever experienced a medical class. The specimen is prohibited from touching, leaving it inconvenient for the professors to make appropriate explanation about the exact location of the pathological part. A laser pointer pen serves as an excellent solution towards this problem by pointing accurately to the point in accord with the professors' intention. And the quality of teaching can in turn get promoted due to the enhancement of the efficiency in course delivering.

The effectiveness of laser pointer pen makes it a widespread gadget in not only medical teaching process, but in other fields of study. In recent years, the appearance of green laser pointers struck the world even more tremendously. Green laser pointers are significantly brighter than a red laser pointer. According to a newly conducted survey, a green laser pointer can be more noticeable than a red one. Were the aforementioned fact cannot persuade you of the advantages of green laser pointers, there would be far more aspects in which the green laser pointer outweighs the obsolete red laser pointer. For one thing, the green laser pointer makes visible the actual beam, due to its particular wavelength that is much shorter than the 650 nm red laser wavelength.

In a word, thanks to the invention of the laser pointer pen, the teaching process becomes more effective and colorful than ever.

For the sake of personal security, it is important to get the necessary tools from durable clothes to useful tools.

When we face the dangerous situation, do you know what measures you may do? If you are planning the journey into the harsh environment, we may need the luster devices providing the light to cope with the extremely dark condition. Here I would introduce the laser pointer.

After working for five years in the consulting company, I become bored in the office work. Since I am always addicted to the natural adventure, I could not wait for any longer to embrace the adventure in tropical forest with the gorgeous waterfall. In order to secure the personal safety, I picked up the green laser pointer with me. After several days, we entered the thick forest. That would be the most beautiful scene I have witnessed in my lifetime. When reaching every beautiful scene on the cliff, by the river and alone the brook, I may stay for a while to take photos. So gradually I got lost from the team before I knew. When the day got darker and darker, I could not tell the direction in the thick forest. I was a little scared with the fact that more dangerous animals may show up in the forest. So I ran quickly in the forest. Unfortunately, I fall into the canyon accidently. Then my legs got injured.

I knew my friends were seeking me everywhere. But I could not move. Then, I realized that I could make use of my green laser pointer to attract them. The hyper-functional laser pointer is with the powerful voltage to release the long-distance luster far away. To my surprise, such laser pointer did not let me down. Half an hour later, my friends followed the light to approach me. After I got rescued, my friends always say such green laser light would be the wonderful medium to find me in the thick forest. To me, it would be unique green luster to save my life.

Introduction to Laser Pointer Pen

During the process of multimedia teaching of popularity, an issue prevails that how to introduce modern teaching equipment which can effectively combine with the teachers' classroom teaching habits. Currently, as teachers make teaching demonstration, they entail escorting their computers. It is essential to explain while they are operating the computers, and where they need to make emphasis, they are obliged to get up from time to time to point the focus. Under these circumstances, the multimedia presentation equipment, whose essence is to facilitate teachers, constrains the teachers' rich classroom language.As a result, advanced teaching equipment has not been fully utilized, instead of affecting the traditional classroom teaching of teachers. There is a similar phenomenon in the teaching medical science. It is acknowledged by the medical students that, as the professors depict the specimen with lesion, they can not touch the specimen, under this environment, the professors can not point the place producing lesion precisely. On that occasion, the teaching quality decreases heavily.

In response to this phenomenon mentioned above, the education industry pays more attention to the modern teaching equipment which can closely connect teachers' enormous teaching experience with habits. That puts forward higher requirements to a variety of informationalized equipment of application in the teaching. Under these circumstances, laser pointer pen comes into appearance.

Laser pointer pen, taking advantage of low-power, visible laser, makes users maximize the advantage of body language in the teaching and demonstration, with the purpose of making lectures, teaching more and more lively and perfect. The laser pointer pen completely solves the inconvenience of using the mouse in the classroom and meeting.

The laser pointer can be divided into three categories, namely, red laser pointer, green laser pointer and blue-violet laser pointer.

Red laser pointer, whose wavelength is usually between the scopes of 650nm-660nm (red), is adopted in the DVD disc. It is the earliest and most popular laser pointer, and its price is generally the cheapest. It belongs to semiconductor laser. The green laser pointer, whose wavelength is generally 532nm, belongs to solid-state laser. Owing to its high degree of visibility, the green laser pointer is widely used in teaching. Blue-violet laser pointer, whose wavelength is generally 405nm, can stimulate fluorescence. It has the role of a money detector, and belongs to a semiconductor laser.

From what has been discussed above, we may safely draw the conclusion that the appearance of laser pointer pen is absolutely convenient to a variety of circles.

Introduction of Laser Pointer

A growing number of people have enthusiasm for the stars. The beautiful sky at night always makes human being intoxicated. The mankind will peer at the stars and identify their statuses, when you can not discern the stars only through your fingers. Under these circumstances, laser pointer comes into appearance.

Laser pointer consists of green laser pointer, red laser pointer and so on.

Green laser pointer is different from the ordinary red laser pointer, whose output brightness is much higher than the latter, that is, the green laser pointer of brightness is several times or more than that of the red laser pointer. When holding the green laser pointer to point the sky at night, you can find a bright green light penetrating the night sky. Astronomers are fascinated by the green laser pointer. Currently, green laser pointer pen is the most popular laser pointer all over the world. Green laser pointer pen of wavelength is 532nm, and the laser type is Class IIIA. Green laser pointer pen demands two batteries. Owing to its extraordinary light, the green laser pointer attacks the eyes to a relatively higher extent, that is, as the power increases on, the jeopardizing of it is more and more heavy. This also requires users to pay special attention to their security, avoiding the touch between the vulnerable sites like eyes and the light of green laser pointer. Users should also prevent the laser from entering into their eyes via reflection.

In that way, for astronomy fans, what style of green laser pointer is wonderful?

In my opinion, the laser pointer of power within 20mW to 50mW is more appropriate, because 50mW power of laser pointer has made you feel especially glaring in the dark conditions. In addition, the laser pointer of power consumption is generally larger. Therefore, in line with the principles of environmental protection and savings, a pair of excellent rechargeable batteries is also very necessary.

From what has been discussed above, we may safely draw the conclusion that the appearance of laser pointer makes people more delighted. And the green laser pointer of higher light determines it to be adopted widely in astronomy. Everything has merits and demerits, so we can not ignore of the disadvantages of green laser pointer. We should do our best to protect ourselves. I believe, with the development of economy, more advance laser pointer will be invented with less danger factors.

Green Laser Pointer

Just imagine this: you are an expert in medical field and now it is your turn to show some special knowledge to your fellow students. In front of you is a body sample, with which you will give your lesson. What's more, the lesson is about the theory of how heart works. Actually, you can not touch the sample with your hand directly, then how will you express the knowledge clearly? The answer is a green laser pointer. If you are not familiar with the new thing, then in the next part of the article you will get some helpful information about this new high tech product.

A green laser pointer is a pointer which points some object with the green laser beam instead of a solid thing, for example, a teaching stick. As a result, the green laser pointer is often in the shape of a laser pointer pen. It just looks like a pen when you do not use it. When you use it to give lessons, the only thing you have got to do is to press the little button on the side of the pen. Then you will see a straight and bright beam shooting from the top of the pen. In the end, just control the beam to point to anything you want to. You will have a wonderful feeling in the process of using the pen because you see the convenience it brings to you.

It is cool, isn't it? It is not all about a green laser pen. We have other funny things about the little product. Since it generates laser beam, we can change the head of the pen to create something interesting. For example, we change a head which can create a beam in the shape of stars. And when we turn on the laser pointer, we see a little star on the cell. If we change it to a heart shape head, we will get a little heart on the cell. So it will not disappoint you only if you have interesting imagination. In other words, it becomes a toy, or a high tech toy, when you are not using it for giving lessons or holding meetings.

And this small thing is powered by two little batteries. By the way, it saves energy, so you do not worry about the frequency of changing batteries. Just enjoy using or playing it!

Many people like watching stars, and the beautiful sky full of stars at the night make people be intoxicated all the time. At such a beautiful night, you will count stars and you will also distinguish who they are. However, you could not point at a star clearly just with your fingers, and other people will also do not know where you are pointing at. At this moment, if you have a green laser pointer pen, you will have a good helper, and it will be your finger to point stars and makes you enjoy beautiful star sky better.

Laser pointer pen gets more and more popular, and it solves many people's inconvenience. The earliest laser pointer pen is red laser pointer pen, and it is used in DVD disks, and it is also very cheap, and nearly all people could afford it.

Green laser pointer pen has 532nm wave length, and it is gained by frequency multiplication of the crystal from infrared light which has 808nm wave length, and it belongs to a kind of solid laser. Duo to green laser pointer pen's high visibility, it is widely used in stars pen.

There are three kinds of laser pointer pens on the market, and they are red laser pointer pen, green laser pointer pen and blue-purple laser pointer pen. Green laser pointer pen has the function to point stars, and it could send out a shinning green light beam in the dark sky and point out right places of stars easily.

In this way, people who like watching beautiful stars could turn to green laser pointer pen for help, and they could point out right places of stars. You could imagine how great you feel when you have a green light beam to point right stars for you in the dark night.

If you have any friends or relatives who show great interest in watching stars, you could consider presenting them a green laser pointer pen, and I am sure that it is the best gift they have received, and in this way they could enjoy beautiful star sky better, and they could find that it is more interesting to watch stars than before.

Therefore, if you want to enjoy beautiful stars better, you must have a green laser pointer pen, and you would fall in love with watching stars from that moment on, and soon you will be familiar with those stars.

Convenience for the Teachers

No matter in what century or what country, the most respectful job is always the teaching job. Through them, the various kinds of knowledge are able to pass to different people and the history of human beings can be remembered. I don't know if you have the same picture in your memory that the well-learned teacher with the gray hair standing in front of the blackboard and talking excitedly about the topics he or she liked a lot. Attracted by his or her emotions, you would follow his or her idea and enjoyed the class a lot.

Scenes like this often pop into my head and I joy them every time I think about such kind of scene. But one thing I don't like badly was that one of my favorite teachers, Betsy, she met troubles at almost every class. She is well-learned and she loves her job so each class, she teaches with enthusiasm. However, she is not tall in height and she has to stand on her toes now and then to point to the blackboard or the projective in order to make her points clearer. It is quite inconvenient both for her and for her students. I was trying to help her solve this problem but couldn't do anything.

However, yesterday, when I passed a stationery store, I happened to notice their new product—laser pointer pen. It is called a pen but it doesn't seem to have a lot to do with the pen. I inquired the shopkeeper and he told me that it was the new product to help the teachers to teach more easily, especially to those who are not so tall. The laser pointer pen is able to project the laser light, which is persistent and direct. It means the teacher can point to the point, either on the blackboard or on the projective from a long distance with the laser light.

Immediately, I bought one of their most popular products—the green laser pointer. The color of the laser light of course is green, and it should be very convenient to be seen in the classroom. I packed the green laser pointer later and sent it to Betsy anonymously. Hope it could do her a great favor and make the teaching even more interesting.

In my opinion, it is so great that people could think more about the teachers and create more convenience for them. Hopefully, more products like the laser pointer pencould be invented soon.

A Laser Pointer - You Need It

In our modern society, many things have experienced great changes gradually. Take the travel as the example, in the past, the concept of travel is to enjoy the beautiful scenery and relax ourselves after a period of hard working. However, in recent, we may find that more and more people would like to choose some risky ones, such as exploration, camping and so on. All of them are full of dangers and risks. People need to go to primeval forest to realize this kind of travel. In this process, they need a light, such as flashlight, electric torch and something like that. But today, I want to introduce a kind of best light which is quite suitable for the exploration and camping. Its name is laser pointer, which plays a vital role during the forest, especially in the night.


Now, let us see some detailed information about laser pointer. Its function comes first. Its main function is lighting. In the night of forest, it can send out a beam of bright light and can let you know what is around you. As we all know, there are dangerous animals, such as snake, tiger or something like that. This kind of laser pointer may save your life at some moment, because it has a strong power and can send the light to the distant place.


Then, I want to introduce three types of this kind of laser pointer. The first one is red laser pointer. Its wavelength is between 650nm to 660nm and it is the earliest version and the cheapest one. Meanwhile, it belongs to semiconductor laser. Then, the green laser pointer. Its wavelength is 532nm and belongs to solid state laser. In addition, it has a very high visual degree. The last one is bluish violet laser pointer, whose wavelength is 405nm. It is close to ultraviolet light and can arouse fluorescence. Meanwhile, it has the function of checking bank note and belongs to semiconductor laser.


The three types that I have mentioned have their own characteristics and advantages. You can choose one from them. But I personally think you had better choose the green laser pointer, which has a much stronger light and more reasonable price. If you want to travel in some dangerous places, you need a green laser pointer most. But just because of its strong light, you should keep your eyes staying away with it, or it will damage your eyes.


Do you want to explore or go camping? If you do, please do not forget a laser pointer.

A Green Laser Pointer Let You Roam in the Star Sea

At the very beginning, I want to ask you a question: have you ever counted the stars in the night? I am sure many people have this experience when they are in their childhood. The starry sky in the night is so beautiful that many people are lost in it. Sometimes, you would like to count them with your lovers, children or parents. Then, what kind of tool that you will choose to count the stars? Your fingers, right? Maybe, just fingers can not distinguish the stars easily. At this moment, you need a pointer. Today, what I want to introduce to you is a kind of green laser pointer, which will let you roam in the star sea in the romantic night.


Now, let us see the brief introduction of the green laser pointer. The main difference of the green laser pointer and red laser pointer is its output light degree is much stronger. In the night, if you use the green pointer pen to pint the sky, you will see a snake of green light beam straight gearing in the starry sky. This outstanding characteristic can let you find out the star that you want to see.


Then, how to choose the power of the green laser pointer is another question. 20nw to 50nw will be fine. If the power is more than 50nw, you will fell the light is so strong that you almost can not open your eyes. In other words, it will be dangerous to your eyes and some other frail parts in your body. The price is another issue that you should pay attention to. Generally speaking, the price is related to the bandwidth and stability. The narrower of the bandwidth, the higher the price. If you just want to use this kind of green laser pointer to enjoy the charming stars, I personally think you had better choose lower power and price one, which will not affect the view effect. In the meantime, the power consumption of green laser pointer is comparatively larger, you need to prepare two rechargeable batteries.


In addition, you may encounter this problem: the green laser pointer can not work in the night even if it works normally in the day. It is because the medium of laser is semiconductor, which is quite sensitive to the temperature. It will not work well in the low temperature. If you come across this problem, what you should do is to hold it by your hands tightly.


Until now, do you have a deeper understanding about green laser pointer? I personally think you need to own one if you love the beautiful starry sky in the romantic night.

A Good Present for Teachers

When people are thinking about their precious time in school, much fond memory will appear in their mind, including the friendship between classmates, the unforgettable experience of studying and the kind and knowledgeable teachers. As a matter of fact, many people will owe their present success and achievements to their teachers, who have taught them much knowledge as well as the principle to conduct themselves, and people will also think of the busy and tired form of their teachers.


Since in the class, in order to give the students a clearer explanation of the knowledge and relevant questions, teachers will use their arms to point to something important and pivotal on the blackboard or the projection, however, it is really inconvenient for them. Seeing that teachers are making every effort to pass on their knowledge to the students, the students should feel very appreciative, and one way to present the kind of appreciation is that they can send their dearest teachers a green laser pointer, which is a high-tech pointer that has been particularly designed for teachers.


A laser pointer pen is a tool with laser as a directing signal, and since it can send a laser that can be seen in a long distance, it can be used to replace a teacher's pointer. As a matter of fact, a laser pointer pen is mainly used in daily work and teaching because of its delicate appearance, light weight, simplicity in operation and convenience to carry.


Green laser pointer is the most popular laser pointer pen in the world, because green light is six times brighter than red light and its price is much lower than that of the blue and yellow ones. Green laser pointer is mainly used in teaching and it is a modernized teaching tool. Since the green laser pointer can send out a continuous beam of light wherever its holder goes, it will bring teachers much convenience. With a green laser pointer in hand, the teachers can be freed on the platform and the ideal condition of "teaching while walking freely in the classroom" can be realized.


When Teachers' day comes, many people will think of sending some present to the teachers that have taught them much knowledge and given them some inspiration in life, and at this time, a green laser pointer will be a good choice, because it can bring them much convenience and help them become less tried in the classroom.

A Good Helper - Laser Pointer

Do you have even heard about laser pointer or laser pointer pen? You must know about them if you know the history of eBay. This e-shop which was established in 1995 has 16 billion users now and it becomes as the best auction website in the whole world. People can buy everything from it except for the prohibited products. The birth of eBay can be attributed to Pierre Palma's fiancée. Because she was worried that she can not collect gadgets after they moved to Silicon Valley. So Pierre Palma established a big auction website to hope that all people can buy everything they want without going out. And the first product which was sold by this website is the laser pointer. Certainly, the laser pointer can be used by many ways today.


Nobody can resist the laser pointer is a good helper for doctor teaching. As we all know, when a professional doctor explains the sample lesions for his students, he can not point the specific parts by hands. Or the dangerous germs will invade into body and cause serious disease. But if he does not point out them, the students can not understand the difficult knowledge. Thus, a laser pointer can help him easily. The clear and straight laser light can find out the specific parts without any risk.


The laser pointers can be divided as three kinds according to different colors. The red laser pointer uses wavelength of 650nm-660nm. It is a kind of laser which is used in DVD disc. This kind of laser pointer is the earliest and most popular and its price is usually cheap at the same time. While the laser light of green laser pointer is always used in blue-ray disc and the feature of this solid laser light is high visibility. The last one is the blue-purple laser pointer, which is widely used to detecting money.


The biggest difference between laser pointer and laser pointer pen is the shape actually. But more teachers, trainers or lecturer intend to choose the laser pointer pen which can help them to demonstrate their lesson and project. Besides, the multimedia is very popular in classroom, so some later pointer pen can be also used as remote control. Teachers can control the computer or projector easily according to course schedule.


But you should use it for a long time, because some powerful laser pointer will have heat effect to hurt others.

A Good Helper for Clinical Teaching

All friends who learn medicine know that the expert could not touch the sample with hands when he is illustrating a pathological sample, and in this way students could not know where he or she explains. In fact, he or she could point the places to people who are listening to his or her lessons smoothly if he or she has a laser pointer pen.


Laser pointer pen is a good helper for clinical teaching, and it could make users to play their body languages to the biggest extent while they are teaching clinical knowledge by means of visual laser in low power, making the teaching and speeches more active and perfect. In this way, laser pointer pen could solve many inconveniences in clinical teaching, and then all people who are listening to lessons could understand better.


Laser pointer pen has several functions, and it has magnifying function in order to attract visual attention to important contents and to improve learning effects. Laser pointer pen also has wireless remote control function, and the expert or teacher could control the computer wherever he or she is at the classroom, and he or she could adjust the contents according to the process of the lesson at any time at any places.


Laser pen pointer could be divided into red laser pointer, green laser pointer and blue and purple laser pointer. Red laser pointer has red light which has 650nm to 660nm wave length, and it is a kind of laser used on DVD disks, and it is the earliest and the most popular laser pointer pen, and it is also the cheapest on the price and belongs to semiconductor laser. Green laser pointer has green light which has 532nm wave length, and it belongs to solid laser, and it is widely used in stars pen because of its high visibility. Blue and purple laser pointer has blue and purple light which has 405nm wave length, and it is used on blue disks and gets close to UV-light, and it could stimulate fluorescence and could be used to check whether money is true or false.


At present, green laser pointer pens get more and more popular in teaching, and experts or teachers could make their classes more active with the help of laser pointer pens. In this way, students could also understand better and learn much more from their experts and teachers.


Laser pointer pen is not only a good helper for clinical teaching but also is a good helper for all teachers.

A Good Assistant in Medical Teaching

As many medical students know, when the medical professor is giving a lecture about a sick specimen, he cannot touch it. So he cannot say clearly about the place that he wants to talk about. If at this time, a laser pointer pen can be used, he will be able to give the lecture more smoothly.


Green light laser pen, just as the name replies, refers to laser pen with green light. It can also be called "green laser pen" or "star pointer pen".


Green laser pointer pen is the most popular laser pointer pen in the world because green laser is 6 times' brighter than red laser. The light beam of green laser is more obvious than the red one, and its price is much cheaper than blue or yellow lasers. Therefore, the users of laser pointer pen usually choose the green one.


The wave length of green laser pointer pen is 532nm and the laser type is Class IIIA. The light of green laser pen is objective so it is more dangerous to people's eyes. Generally speaking, 5mw green laser pens are used generally. In America, only 5nm laser pen can be sold on the market. If the power is over 5nm, the seller must get special admission for the sale of the pen. In China, there is no strict limitation about the pen, so we need to pay more attention to our safety.


Green laser pens are usually used in teaching. It is a modern teaching mold or equipment. Teaching laser pen is the third generation of written laser pen. In demonstrating lecture or project, sometimes teachers, trainers or speakers need to operate the computer while they are explaining something to others. It is very inconvenient because their actions are limited. How to liberate teachers completely? The appearance of laser pen solves this problem.


For astronomers, which kind of laser pens will satisfy their needs to point stars? What about the power or the price? Personally speaking, 20mw and 50mw are proper. In the gloomy room, the light of laser pen with more than 50mw power will be very dazzling. The price of laser pen is mainly related to its broad band and stability, the narrower of the broadband, the more expensive of the pen. However, it is impossible for people to tell apart the difference between broad bands. Therefore, people who have not enough money can choose laser pens with power below 50mw and with the price under 100RMB. In addition, the power consumption of laser pen is large. On the principle of environmental protection and energy - saving, it is necessary to buy a pair of good rechargeable batteries.

If you need, it is very worthwhile to buy a laser pen.

The Necessary Item for Amateur Astronomers

A laser pointer pen is necessary for an amateur astronomer, because it can help you to find out the star you like in the night sky. Just like the navigator of the vast sky. How to choose the laser pointer pen as an amateur astronomer? As there are various kinds of laser pointer pens in the market. In fact, the power and price are the most important factors you should take into consideration. As far as I am concerned, I think the laser pointer pen whose power is ranging 20mW-50mW is suitable. Those laser pointer pens whose power is higher than 50mW are very glaring even in the dusky environment. And people can find that the laser pointer pens can be divided as red laser pointer and green laser pointer in the shop. Generally speaking, the output power of green laser pointer is far higher than red laser pointer which means it is brighter in the night sky. The amateur astronomers should choose the green laser pointer pen though it is more expensive than the red one.

The price of laser pointer pen is often related with the bandwidth and stability. The narrower the band is, the more expensive it will be. But I suggest you to select the laser pointer pen whose power is lower than 50mW and price is lower than 20 dollars since the naked eyes can not distinguish the difference.

Besides, the high power means the high electricity consuming. If you buy the expensive laser pointer pen, you should prepare more batteries at the same time. It is not economical and environmental certainly. But if you need this kind of laser pointer pen indeed, maybe a pair of rechargeable batteries can help you to deal with this problem.

Finally, some people may find such problem: why the laser pointer pen always runs out in the night even it works normally in the day? The truth is the media of laser pointer pen is semiconductor which is very sensitive to temperature. It can not work if the temperature is too low, so you just need to cover it by hands before you use it.

I would like to remind you the risk of laser pointer pen, because even low powered laser pointer pen can burn through the plastic bag in 0.5 meters. Especially, you must put it away from children. If the children point to other people's eyes by laser pointer pen for a while, it will burn out their eyes. It is very dangerous.
