Nd:GdVO4
Neodymium doped Gadolinium Orthovanadate single crystal (Nd:GdVO4 crystal ) 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.
Advantages:
1. Large stimulated emission cross section at laser wavelength
2. High absorption coefficient and wide bandwidth at pump wavelength
3. Low dependency on pump wavelength
4. Good thermal conductivity
5. Low lasing threshold and high slope efficiency
6. High laser induced damage threshold
7. Strongly-polarized laser output
