Cr⁴+:YAG Laser Crystal Chromium Doped Yttrium AIuminum Garnet Crystals Customizable
Cr⁴+:YAG (Y3Al5O12) is an ideal material for passive Q-switching of Nd:YAG and other Nd and Yb doped lasers in the wavelength range of 0.8 to 1.2 mm. One of the remarkable features of Cr4+:YAG is high damage threshold (better than 500 MW/cm2). Passive Q-Switching is preferred for simplicity of manufacturing and operation, low cost and reduced system size and weight.
