What are the functions of various color laser pointers?
A laser pointer is a tool that uses a high powered laser as a pointer. These are always long distances and can be used as a substitute for presentation tools when reading slides. With a laser pointer, the laser spot can be seen from tens of meters away, so the laser pointer is often used as an indicator. Most current laser pointers are red, green, and blue. They are small, but still expensive. The laser pointer has red, green, blue, and purple light; different beam colors represent the colors emitted by lasers of different wavelengths. For red light: a solid-state diode pumped laser with a wavelength of 671 nm. For yellow light: The wavelength is 593.5 nm. Green light: 808nm infrared laser is used. For blue light: This is a 473nm blue laser manufactured by DPSS. Violet: Blue-violet laser diode with a wavelength of 405nm is used, which is a semiconductor laser and is close to the ultraviolet band.

One is not to use the laser pointer indiscriminately. What type of situation is specific to its use, we cannot confuse with it. When we buy a laser pointer, we must go to a trusted company or store. It should have a brand logo, especially for some high-power laser pointers. Don't let children use it. If you use a laser pointer over 5mW, please prevent the beam from entering human eyes. In construction and stargazing projects, laser pointers are very suitable for pointing. They also provide opportunities to play with animals. In fact, laser pointers come in many colors, common colors include red and green. In addition, the maximum power can reach 7W, and the super laser can be used in the military industry.
