Introduction
ZnGeP2 single crystals are designed for laser frequency conversion from one spectral range to another one and can be used for:

1. creation of optical parametric oscillators (OPO) — coherent radiation sources tunable within 2.5—12 micron spectral range when pumping with a laser radiation of 2um wavelength;
2. generation of СО- and СО2-laser radiation harmonics;
3. generation of radiation of both sum and difference frequencies from СО, СО2 and other middle IR range lasers radiation (1 - 11 µm).
   
   ZnGeP2's Applications:
   Coherent radiation sources tunable in 2-11 µm spectral range based on parametric frequency conversion of laser radiation allow solving a number of applied problems of high-resolution spectroscopy:

• remote monitoring of industrial and anthropogenic emissions to the atmosphere;
• remote identification and monitoring of concentration of various toxic gas mixtures and gaseous products or industrial discharge in power engineering, chemistry, and petroleum industry;
• creation of detection systems for monitoring of pipeline breaking;
• design of warning systems for explosive mixtures (methane);
• control and certification of high-purity gases used in microelectronics and semiconductor engineering;
• monitoring and control of special technological processes, for example, annihilation of toxic agents.
