Cr4+: YAG CRYSTALS
 
 
Cr4+:YAG is an excellent crystal for passive Q switching of Nd:YAG, other Nd and Yb doped lasers, in the wavelength range from 800 nm to 1200 nm. Because of its chemical stability, durability, good thermal conductivity and high damage threshold (> 500 MW/cm2) and being easy to be operated, it can replace traditional LiF, Dye and color centers which are commonly used as passive Q-switching materials. Cr4+:YAG is also an useful lasing material, with output from 1350 nm to 1600 nm(tunable).
