Zinc-Germanium Diphosphide (ZnGeP2, ZGP) single crystals are highly-effective non-linear optical crystals for the mid-IR as well as terahertz range. ZnGeP2 crystals have positive birefringence which allows to carry out phasematched parametric frequency conversion of optical radiation in all the ranges of their background transparency spectrum from 0.75 to 12.0 μm. Its useful transmission range lies from 1.9 to 10.6 μm with absoprtion of lower than 0.05 cm-1 @ 2.05 μm. ZnGeP2 has large non-linear optical coefficient and a relatively high laser damage threshold.
varna Second, third, and fourth harmonic generation of CO2 laser
varna Optical parametric generation (OPO) with pumping at a wavelengths of 2.05-2.94 μm and possibility to generate effectively 3-10 μm ranges
varna Second harmonic heneration of CO-laser
varna Producing coherent radiation in sub-millimetre-range from 70.0 μm to 1000 μm - terahertz range
