What's the most powerful laser pointer in existence?
If used safely, green laser Pointers can provide you with multiple benefits. You can use it as a pocket friend on trips or as a professional tool for any presentations you present at the office. High-power laser Pointers can be used for a variety of purposes. The red laser designator projects light directly from the laser diode. However, the green laser designator emits through a non-linear crystal (KTP crystal), which causes the conductor to convert wavelength from 1064nm infrared light projected from semi-infrared to 532nm green light. Green laser Pointers do not emit light directly from laser diodes. Due to the high price of KTP crystal, the finished product of DPSS laser is much lower than the laser pointer made by ordinary diode. Therefore, the cost of a green laser pointer is much higher than that of a red laser for the same output power.

The conversion efficiency of green light at 532nm is very low, less than 10%. For example, a 500mW infrared laser diode provides a 50mW green laser indicator. The 200mW green laser pointer can achieve similar visual effects to the 20mW green laser pointer, and the power consumption of the two lasers is almost the same. However, green laser Pointers are much safer to use. Astronomical laser designators are usually green beams, which is the vast majority of the case, but there are other tools that use other rays, such as stars, such as blue. In addition, the astronomical laser pointer should have a long range feature, which ensures that you can point at more sky and have a better astronomical experience.
