Product Features

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 han Nd:YAG crystal and better thermal conductivity, higher power output than Nd:YVO4 crystal.
