Description

Details

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 2.1 to 10.6 µm with absoprtion of lower than 0.04 cm-1. ZnGeP2 has large non-linear optical coefficient and a relatively high laser damage threshold.
Features
  • Second, third, and fourth harmonic generation of CO2 laser
  • Optical parametric generation with pumping at a wavelength of 2.0 μm
  • Second harmonic heneration of CO-laser
  • Producing coherent radiation in sub-millimetre-range from 70.0 μm to 1000 μm - terahertz range
  • Generation of combined frequencies of CO2 - and CO-lasers radiation and other lasers are working in the crystal transparency region
