Nd: GdVO4 Crystals
Nd: GdVO4 crystals are excellent laser crystals. They are ideal laser host materials for diode pumped solidstate (DPSS) micro/mini lasers because of their good physical, optical and mechanical properties. They have higher slope efficiency than Nd: YAG crystals and provide better thermal conductivity and higher power output than Nd: YVO4 crystals, so they are a good choice for high power output DPSS lasers. Using advanced growth technology,Casix provides high grade Nd: GdVO atm% to 4.0 atm%. In addition, crystal components of various sizes and coatings are available. 4 crystals with Nd doping from 0.1 atm% to 4.0 atm%. In addition, crystal components of various sizes and coatings are available.
