Conversion efficiency of 532 green laser pointer
Unlike the laser pointer made by direct diode, the laser conversion efficiency of the 532nm green laser pointer is not 100%. All green laser pointers should be added to the laser beam filter to prevent 1064nm IR laser. The actual output power of the green laser pointer should be the power of the 532nm green laser. Sometimes, the DPSS green laser provided by the high power laser pointer supplier has a mixed output power of 532nm and 1064nm instead of a separate 532nm laser power. In fact, the 532nm green laser pointer without infrared filter does not reach the actual output power it should. Pick up a flashlight or smartphone flashlight and turn it on at sunny times of the day. You will of course see that it is not so obvious compared to the other darker parts of the day. The same applies to handheld laser pointers, so if you need the beam to be visible at 100 meters, there are a few things you must keep in mind.

The power should be turned off after the 532nm green laser pointer has been pointed continuously for a certain period of time. However, the red laser pointer does not need to do this. The design of green lasers has high power consumption and large heat generation, which will be affected when the operating temperature is too high. In addition, the 532nm green laser pointer can automatically cut off the power when the working temperature is very high to protect the green laser pointer pointer diode from being burnt out. Generally, the green laser pointer has an output direction of 532nm laser wavelength, which is obtained from the 1064nm infrared laser frequency. It is the most common DPSS (diode-pumped solid-state frequency doubled) laser and is more complex than laser pointers made by standard laser diodes (such as red, blue, or blue-violet laser pointers). The 532nm green laser pointer projects the most obvious and brightest green light at night and during the day.
