  • htpow htpow Frequency Doubled Green Laser At night, due to the Rayleigh scattering of atmospheric molecules, even low-power green light can be seen. Astronomy enthusiasts often use this laser pointer to point at the stars and constellations. The green laser pointer can have multiple output powers. 5mW is the safest way to use it. It can be seen under darker lighting conditions, so no higher power is needed for pointing. Green Laser Pulse, Nonlinear Crystal, Solid Laser Operating laser pointer under various conditions The infrared  Laser pointer  excites the nonlinear crystal to produce 1064nm infrared light, and after frequency multiplication, it produces 532nm green light, which is a solid laser. Some green lasers operate in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. It is announced that green lasers that do not require frequency doubling have higher efficiency. At night, due to the Rayleigh scattering of atmospheric molecules, even low-power green light can be seen. Astronomy enthusiasts often use this laser pointer to point at the stars and constellations. The green laser pointer can have multiple output powers. 5mW is the safest way to use it. It can be seen under darker lighting conditions, so no higher power is needed for pointing. The infrared remote control  laser engraver  has basically been eliminated. The reason is that they must be consistent with the operating direction. In addition, they are susceptible to interference from other infrared light (such as fluorescent lights and sunlight) and have a short operating distance. Radio frequency remote control is a mainstream wireless technology. Its advantage is that it has no directional restrictions and has a long operating distance. You can use it freely without restriction. The radio frequency technology remote control  blue laser pointer  is divided into 433MHz/315MHz low frequency technology and 2.4GHz high frequency technology. The disadvantage of the 433MHz/315MHz low frequency band is that because it is the same as the computer part of the operating frequency, it is susceptible to interference, which leads to a shortened control distance and occasional inoperability, which brings work inconvenience. Many car wireless door locks are also in this frequency band. When choosing, be sure to ask the dealer clearly. 4GHz technology is currently the most advanced wireless technology in the world and has the strongest green interference capability. It has the ability to automatically detect frequency hopping, thereby avoiding mutual interference. Even if the same frequency band exists in the same surrounding environment, it will automatically detect and select another frequency point to work.
