Laser Physics
For example, a commercial green laser pointer powered by two AAA batteries contains an 808- nm laser diode that pumps a Nd : YVO4 (neodymium-doped yttrium … … oxide phosphate, KTiOPO4) to generate a few milliwatts of green ( 532 nm) light in a … In end-pumped DPSS lasers, diode laser radiation is injected through an end facet of the laser …

Spatial coherence of low-cost 532nm green lasers
The DPSS laser resonant cavity is terminated by a dielectric mirror that reflects at 1064 nm and transmits at 532 nm. An infrared filter behind the mirror removes infrared radiation from the output beam (this may be omitted or inadequate in less-expensive " pointer -style" green lasers), and the assembly ends in a collimator lens 1 .

Nd:YAG laser - Wikipedia, the free encyclopedia
For many applications, the infrared light is frequency-doubled or -tripled using nonlinear optical materials such as lithium triborate to obtain visible ( 532 nm , green ) or ultraviolet light. A green laser pointer is a frequency doubled Nd:YVO4 diode-pumped solid state laser ( DPSS laser).

In this investigation, three different colors, red, green , and blue-violet laser pointers (maximum power of 5 mW), were used as light sources, and they were coupled with an optical fiber as shown in Fig. 4.11(b). For example, a diode-pumped solid-state ( DPSS ) laser module consists of a powerful 808 nm IR diode laser that pumps a Nd:YVO4 laser crystal, generating 1064 nm light. This fundamental is frequency doubled to 532 nm by passing through a non-linear Potassium Titanyle Phosphate .
