Where is the use of the green laser pointer?

The green laser pointer can emit a bright, highly visible green laser beam and spot, which is the most sensitive Green laser pointer for human eyes. The brightness of the green laser pointer is five times that of the red laser. The 808nm infrared laser is used to excite the nonlinear crystal to generate 1064nm infrared light, and then to generate 532nm green light after frequency doubling, which belongs to the semiconductor pumped solid-state laser (DPSS). Some green lasers work in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. The recently announced green lasers that do not require frequency doubling have higher efficiency. Common wavelengths are 520nm and 525nm. Even low-power green light can be seen at night due to the Rayleigh scattering of atmospheric molecules. This laser pointer is often used by astronomy enthusiasts to point stars and constellations. The green laser pointer can have a variety of output powers. 5mW (category a) is the safest to use and can be seen under dimmed lighting, so stronger power is not needed for pointing purposes.

The DPSS laser used by the green laser pointer is a new generation of solid-state laser with many advantages such as long life, low power consumption, high stability, good beam quality, and miniaturization. DPSS lasers have been used in optical fiber communications and space communications. , Environmental science, atmospheric research, laser printing, medical equipment, optical image processing and many other high-tech fields. This is a new type of laser with a wide range of applications. It has developed rapidly internationally in recent years. It makes solid-state lasers have a brand-new development, so it is also called "second-generation lasers." The green laser pointer is also known as the star pointer, Laser pointer, green pointer, and handheld laser. It is named because of its very intuitive visible and strong beam, which is mostly used for pointing purposes. Because of its bright beam and strong resistance to stray light interference , And is used more and more for teaching/astronomy pointing stars, fixed-point guidance, etc. It is the equipment for the majority of laser lovers/astronomy enthusiasts and outdoor activity enthusiasts. It can also be used as a gift for relatives and friends.
