Zinc-Germanium Diphosphide (ZnGeP2) single crystals are the highly-effective non-linear optical material for the middle IR-range. ZnGeP2 crystals have positive birefringence which allows one to carry out the phasematched parametric frequency conversion of optical radiation in all the range of their background transparency spectrum from 0.75 to 12.0 µm.

APPLICATIONS of nonlinear single crystal Zink-Germanium Diphosphide (ZnGeP2):

- Second, third and fourth harmonic generation of CO2-laser
- Second harmonic generation of CO-laser
- Generation of combined frequencies of CO2- and CO-lasers radiation and other lasers are working in the crystal transparency region
-. Optical parametric generation with pumping at wavelength 2.0 µm
- Producing coherent radiation in submillimeterrange from 70.0 µm to 1000 µm
