Cr4+:YAG
Passive Q-Switching is preferred for simplicity of manufacturing and operation,low cost and reduced system size and weight .Cr4+:YAG 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 0.8 to 1.2μm.
Advantages of Cr4+:YAG Crystals:
l Providing high power laser pulses without electro-optic Q-switches
l Good thermal conductivity
l High damage threshold
l More robust and stable than dyes or colorcenters
l Sizes--Diameter:3~12mm H×W:2×2~30×30mm
l Polished and AR coated
l Initial transmission 5%~95%@1064nm
