Laser Crystals
      Laser crystals are used to generate laser radiation. The commonly used laser crystals include Nd:YAG, Nd:YVO4 for near IR lasers, and Ti:Sapphire for tunable near IR output. Specifically, Nd:YVO4, for diode pumped solid state lasers were developed because diode pumping attracts more and more interest of both R&D and OEM customers. Simphoton provides laser crystal such as: Nd:YVO4, Nd:YAG, Gr:YAG, etc. We also provide a complete kits of optics (Laser mirros and couplers) for your whole laser system.
