Nd:GdVO4

Strongly - polarized laser output. 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.

Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, the gadolinium vanadate have produced a higher slope efficiency or optical conversion than Nd:YVO4.
