520nm light green laser pointer torch , grass color green laser pointers.

The laser torch is not common in the market because of the wavelength of 520nm. The beam is grass green, which is more special than the traditional ones. In addition, this new style is the waterproof one with the stainless steel cover. More beautiful, smaller, easier to carry. This is the most powerful green Laser torch .

The laser from a 532nm green laser torch is produced by the frequency doubling of the laser crystal. While the laser from a 520nm light green laser torch is generated by a semiconductor laser diode (with the wavelength of 520nm). The two laser torch have different spot modes, and different laser dot target. The 532nm laser is a TEM00 laser, and the beam quality is better.
