Neodymium doped Gadolinium Orthovanadate single crystal (Nd:GdVO4) is an excellent laser crystal. This crystal is ideal laser host material for the DPSS (Diode pumped Solid State) micro/mini lasers as its good physical, optical and mechanical properties. It has higher slope efficiency than Nd:YAG and better thermal conductivity, higher power output than Nd:YVO4, so it is a good choice to use Nd:GdVO4 for high power output DPSS lasers.

The main advantages of Nd:GdYO4 as a laser host:
Large stimulated emission cross section at laser wavelength;
High absorption coefficient and wide bandwidth at pump wavelength;
Low dependency on pump wavelength;
Good thermal conductivity;
Low lasing threshold and high slope efficiency;
High laser induced damage threshold;
Strongly-polarized laser output.
