The 520nm Light Green Laser Pointer is different to the traditional regular 532nm dark green laser pointer.

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