Description
ZGP | Infrared Crystal (ZnGeP2, ZGP) single crystals are highly-effective, non-linear optical materials for the middle IR. These crystals have positive birefringence which allows one to carry out the phase matched parametric frequency conversion of optical radiation in all the ranges of their background transparency spectrum from 0.74 to 12.0 µm. Their useful transmission range is from 1.9 to 8.6µm and from 9.6 to 10.2µm.
KEY FEATURES
- Large nonlinear optical coefficient
- High laser damage threshold
- High thermal conductivity
- Stable mechanical properties
- Phase matching ability over a broad spectral region
MAIN APPLICATIONS
- Second, third, and fourth harmonic generation of CO2 and chemical DF-laser
- Optical parametric generation with pumping at a wavelength of 2.0µm
- Up-conversion of CO2 and CO laser radiation to near IR range via harmonics
- Generation and mixing processes
