Hot Selling for Laser Lamp - ZnGeP2 Crystals – Dien Detail:

Zinc Germanium Phosphide (ZGP) crystals possessing large nonlinear coefficients (d36=75pm/V). Our ZGP has wide infrared transparency range(0.75-12μm), useful transmission from 1.7um. ZGP also shows high thermal conductivity(0.35W/(cm·K)), high laser damage threshold (2-5J/cm2)and well machining property.

ZnGeP2 (ZGP) crystal was called the king of infrared nonlinear optical crystals and it is still the best frequency conversion material for high power, tunable infrared laser generation. DIEN TECH 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). These properties enables ZGP crystal to be used to generate mid-infrared tunable laser with high efficiency through OPO or OPA processes.

Applications of ZGP:

• Second, third, and fourth harmonic generation of CO2-laser.

• Optical parametric generation with pumping at a wavelength of 2.0 µm.

• Second harmonic generation of CO-laser.

• Producing coherent radiation in submillimeterrange from 70.0 µm to 1000 µm.

• Generation of combined frequencies of CO2- and CO-lasers radiation and other lasers are working in the crystal transparency region.

Orientation of ZGP:
The standard ZGP crystal orientation is for type I phase matching at an angle of θ= 54° , which is suitable
for use in OPO pumped at wavelengths between 2.05um and 2.1um to generate mid-infrared output
between 3.0um and 6.0um.

Custom orientations of our ZGP crystals are available on request.
