Crystal ZnGeP<sub>2</sub> for Nonlinear Frequency Conversion: Physical Parameters, Phase-Matching and Nonlinear Properties: Revision
Abstract
The article presents a comparative analysis of published data for the physical parameters of the ZGP (ZnGeP2) crystal, its nonlinear and phase-matching properties, and functional capabilities for all frequency conversion processes (harmonics, sum and difference frequencies, and parametric generation). At the first time, the possibilities for obtaining the temperature-noncritical processes for some combinations of wavelengths are shown.
