Nd:GdVO4
(Nd doped Gadolinium Orthovanadate)
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 followings are 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.
