Cr:YAG

Chromium Doped Yttrium Aluminum Garnet (Cr4+:YAG) Crystal is excellent E-O material for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 and other Nd (or Yb) doped lasers at wavelength 0.8~1.2µm. With diverse advantages of chemically 

stable, durable, UV resistant, good thermal conductivity, high damage threshold ( >500 MW/cm2) and easy to be operated, 

Cr4+:YAG is edging out traditional materials, such as LiF, organic Dye and color centers.
