Nd:GdVO4

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. Features including:

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. Recently,Nd:GdVO4 Series including Tm:Ho:GdVO4, Er:GdVO4, Yb:GdVO4 etc., and steadily provides as ¦Õ5¡Á70mm, ¦Õ4¡Á65mm, ¦Õ3¡Á60mm rod crystal.real high quality Nd:GdVO4, Er:GdVO4, Yb:GdVO4, Tm:Ho:GdVO4 crystals at very competitive prices with our automatically-control advanced crystal grown technology
