Yb:YAG Crystals, 1%Doping, Brewster cut

Yb3+:YAG crystals are laser crystals for diode or laser pumped solid state laser applications. Its quantum defects are only about 9%. The Yb:YAG crystal also has a broad pump band around 940 nm, which is more than 10 times wider than the 808 nm pump line width of the Nd:YAG crystal. We can provide Yb3+:YAG crystals in various specifications.
