Nonlinear Optical Crystal-ZNGEP2 Crystal ZGP

ZGP crystals possessing large nonlinear coefficients (d36=75pm/V), wide infrared
transparency range(0.75-12μm), high thermal conductivity(0.35W/(cm·K)), high laser
damage threshold (2-5J/cm2)and well machining property, ZnGeP2 crystal was called the king of infrared nonlinear optical crystals and is still the best frequency conversion
material for high power, tunable infrared laser generation.
We can offer high optical quality and large diameter ZGP crystals with extremely low
absorption coefficient α < 0.03 cm-1(at pump wavelengths 2.0-2.1 µm), which can be used to generate mid-infrared tunable laser with high efficiency through OPO or OPA processes.
