Nd: GdVO4 crystals are excellent laser crystals. They are ideal laser host materials for diode pumped solid state (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.
