A longer battery laser pointer beam?
This action takes place in the optical cavity. When the photons that attenuate in the direction of the mirror (most of them are lost-the laser is not as effective as you think) reach the end of the laser, they are reflected back into the material, where the chain reaction continues and the number of photons increases. Using infrared laser with a wavelength of 808nm to excite the nonlinear crystal to produce 1064nm infrared light, and then multiplying by the 532nm green light, it belongs to the solid-state laser. Some green lasers operate in pulsed or near continuous mode to reduce cooling problems and extend battery life. Announcing the need for double-frequency green laser pointer with higher efficiency. When the photon reaches the partial mirror, only a part will be reflected back to the cavity, and the rest will appear as a laser beam.

At this wavelength, the human eye is more sensitive to green light, and the high powered laserwill appear brighter. The human eye's estimate of the sensitivity of the green laser is 10 to 50 times that of the red laser. The best practice is to use a red laser pointer and follow all safety guidelines from the manufacturer. The price of the super laser will range from US$40 to US$100 depending on its wattage, and there are many options to choose from. A working voltage of 3 to 4 watts means that the beam is very strong and can reach the sky directly. The best part is that they are small, easy to carry, and can be put in a pocket or purse at any time. Who knows, you might also find new uses for laser pointers. In fact, recently I was surprised to find that the green laser pointer can also be easily used to signal the origin and constellations. No wonder researchers use these astronomers in discussions or presentations. I think there is no other way to accurately point to celestial bodies before.
