With the exception for communications, night vision, warning, distance, etc., the variety of laser weapons and laser-guided weapons has also been put into practical use.
In the future, with further human laser technology research and development, will further improve laser performance, the cost will be further reduced, but it will continue to expand the scope of application is, and will play an increasingly significant role.green laser pointer is a speech assistant.
Laser Pointer
Laser pointer is the use of laser as an indicator of small, low-power laser, a general civilian goods, also known as laser pointer, Pointer pen. Is a versatile product: teaching, research units as teaching, research papers, conferences and so forth with the use of video equipment as instructed; military units with large-screen command system for instructions; tourism units for guided tours; construction and renovation supervision units for construction, renovation acceptance of instructions and so on. The green laser pointer turns pages with the help of radio frequency.Some cases can also be fixed as a directional tool; also as a gift.
Types of lasers
1 gas lasers
In gas lasers, the most common is helium-neon laser. The world's first helium-neon laser is the second shortly after the first ruby laser in 1960, Bell Laboratories in the United States by the Iranian physicist Jia Wan made. As the helium-neon laser emits monochromatic beam direction and good, can work, so this laser is the most used lasers today mainly used in the holographic precision measurement, collimator positioning.
Gas lasers is another typical argon ion laser.green laser pointer is the right hand of teachers. It can send bright blue-green shade, continuous work, the output power of 100 watts. Such lasers in the visible region is the highest output power of a laser. Because of its blue-green laser is emitted, so the most used on the eye, blue-green because the human eye's response is very sensitive to the retinal heme, lutein can absorb green light. Thus, argon ion laser eye surgery, can rapidly form a local heating, the protein into a gel state of the retina, which is the ideal light source for welding the retina. Argon ion laser emits blue-green laser can deep sea floor, without being absorbed by seawater, which can be used underwater survey operations.
(2) liquid, chemical and semiconductor lasers
Also known as liquid laser dye laser, because the activation of these lasers is that some organic dye material dissolved in ethanol, methanol or water and other liquids in the form of the solution.You can turn pages at anywhere you stand in the classroom with the green laser pointer. In order to stimulate them to emit a laser, commonly used for high-speed flash laser source, or by other laser emits very short pulses of light. For liquid laser emits laser spectroscopy, laser chemistry and other scientific research, is of great significance.
Chemical laser is a chemical reaction to generate the laser. Fluorine atoms and hydrogen atoms, such as chemical reactions, can generate hydrogen fluoride molecules in the excited state. Thus, when the two gases mix quickly to be able to produce the laser, so no other energy can be obtained directly from the chemical reaction is very strong light. green laser pointer is an excellent electronic assistant.These lasers are more suitable for field work, or for military purposes, it is fear of death ray weapon is a result of application of chemical lasers.
