Cr4+ :YAG(Chromium Doped Yttrium AIuminum Garnet)
Cr4 :YAG (Cr4 :Y3Al5O12 ) is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Yb:YAG or other Nd and Yb doped lasers at wavelength from 1.0 to 1.2 mm. Because of its chemically stability, durability, UV resistance, good thermal conductivity and high damage threshold (> 500 MW/cm2) and ease of use, it replaces traditional materials, such as, LiF and Organic Dyes. Standard size of 3X3mm with To = 80% or 90% are readily available.
