A. Diode-Pumped Solid-State (DPSS) LASERS are solid-state LASERS made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a LASER diode. The most common DPSS LASER in use is the 532 nm wavelength green Hand-Held LASER. A powerful (<200 milliwatt) 808 nm wavelength infrared LASER diode pumps (provides energy to) a neodymium doped yttrium orthvanadate (Nd:YVO4) crystal which produces 1064 nm wavelength light. This is then frequency doubled using a nonlinear optical process in a KTP crystal, producing 532nm coherent light.
