The ideal laser pointer for everyone!
A strong green laser (wavelength 532 nm (1 nanometer = one billionth of a meter)) is impossible because there is no green laser diode. So you have to take a detour: very powerful laser diodes (up to 500mW) with a wavelength of 808 nm (infrared) excite a special laser crystal (Nd:YVO4) to emit infrared radiation at a longer wavelength of 1064 nm. The second high power laser pointer beam in turn passes through another crystal, which doubles the frequency, halving the wavelength to 532nm (light green). This is followed by optical and infrared filters and sensors for performance monitoring and control. This is called a DPSS laser (diode pumped solid state). The crystal itself is very expensive and difficult to tune in a small pointer package. So the price is relatively high.

5000mW high power makes this 5000mW 532nm beam light green 5 in 1 green laser pointer kit capable of handling a lot of cool stuff. It produces a Class 3a laser pointer with a super-bright green spot full of energy. So you can use it to light a cigarette or make a fire. In addition, it supports focus adjustment and starry sky effect. Low power consumption, using 18650 battery, can provide long-term continuous use.
Is a 5 MW laser pointer legal?
According to Wikipedia up to 5mW, but otherwise good for universities or licensed people, but even 1mW is enough to hurt the eyes! ! ! Even with 5 mW, you can seriously damage your (and other) eyes! ! ! So: if you don't have to, let it go! Yes, the maximum allowable power of the laser is 5 mW, if you are looking for a laser that is clearly visible, look for a laser with a stronger wavelength (800 nm), but be careful! With 5 mW, you can already do something,
