Nd:GdVO4 Crystals

Neodymium doped Gadolinium Vanadate (Nd:GdVO4 Crystals) is an excellent  ideal laser host material for the DPSS (Diode pumped Solid State) micro/mini lasers due to  its good physical, optical and mechanical properties. It offers higher slope efficiency than Nd:YAG crystal and better thermal conductivity, higher power output than Nd:YVO4 crystal.
 

Main advantages of Nd:GdYO 4 Crystal:
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
