The wavelength of the green laser pen is also 808nm, and the green laser with 532nm is generated after frequency doubling. Moreover, the green laser has a good display effect at night, and the cooling phenomenon can be reduced by pulse or continuous mode, so the green laser pen has a long service life. Moreover, there are many kinds of output power of the green laser pointer, each of which has different effects. The most used and safest power is 5MW.
