The mystery of science is infinite, and the wisdom of people is also infinite, so a variety of high-tech modern equipment and tools appear and progress at an unexpected speed, providing guidance and help to various fields and industries in the world. Take, for example, the green laser we're talking about today. We all know that green laser is one of the many lasers, green laser is able to emit and transmit a green laser instrument, widely used in life, today we will take a specific look at this high-tech products.
About:
Also known as star pen, laser pen, handheld laser. Because it has a very intuitive visible strong beam, mostly used to indicate the role of the name, because of its bright beam, anti-stray light interference is strong, and is more and more used for teaching, astronomical star pointing, fixed-point guidance and other functions. It is the preferred equipment for laser enthusiasts, astronomy enthusiasts and outdoor activity enthusiasts. Can also be used as high-grade gifts for friends and family.
How it works:
The wavelength of 1064nm infrared light emitted by the infrared semiconductor laser is converted by nonlinear crystallization to emit 532nm green light. Green light is not emitted directly from a semiconductor laser. In addition, as a green laser, there are also nonlinear crystallization to make the infrared light from solid lasers such as YAG lasers emit green light. The above lasers have the problem that the luminous wavelength is limited to 532nm, and the power conversion efficiency is low because the wavelength is to be converted.
Product use:
1. Teacher/lecturer - for classroom teaching, it is like an infinite extension of the pointer, so that you can easily point the blackboard in any corner of the classroom, is definitely the right hand of teachers!
2. Business person/conference speaker - Used for product presentations and conference explanations, so that your speech becomes more spontaneous, and the communication with customers is more relaxed and natural.
3. Exhibition Hall/Guide - It can help you easily and accurately indicate the target when you are helpless in the face of "unreachable" goals.
4. Wilderness Traveler/Explorer - Used for wilderness exploration, indicating distant targets and sending distress signals to make your trip happier and safer.
5. Astronomy enthusiasts - for astronomical stars, the green laser beam is a very beautiful green line, which is suitable for observing the stars at night and can help you point out the position of the stars.
6. Construction sites/mining sites - Used to accurately indicate buildings from a distance, which can avoid approaching dangerous areas and allow you to command as if you were in the field from kilometers away.
7. Self-defense - When you encounter a dangerous animal attack in the mountains, or when a gangster robberies you, and poses a threat to your life and property, you can use it for self-defense.
You may sometimes find that green things appear brighter, which is actually because the human visual nerve is very sensitive to green. Researchers use this principle to develop green lasers, which are widely used in the education industry, security fields, and military bases, but Xiaobian should remind you that the long-term exposure of green lasers can make people dizzy, especially the children's retinas are fragile, and may also make children blind, so don't let children play.
