Cr YAG Q Switch Crystals

Cr4+: YAG is a crystal that is used for passive Q-switching in lasers, and it is also an new laser material. It is applied in the range of 900-1200 nm and 1350-1600. Cr4+:YAG is an excellent saturable absorption material for Nd and Yb doped lasers(especially for Yb: YAG laser, Nd: YAG laser or Nd:YVO4 lasers)
