Abstract

The Sellmeier equations for GaS and GaSe are constructed from the nonlinear experiments thus far reported in the literature. The model calculations based on these equations were found to reproduce well the phase-matching conditions for second-harmonic generation of the Er:YSGG laser at $2.7960\mathrm{\mu m}$ and the ${\mathrm{CO}}_2$ laser lines at 9.5862 and $10.5910\mathrm{\mu m}$ achieved in the ${\mathrm{GaS}}_x{\mathrm{Se}}_{1-x}$ crystals having different S concentrations of $0.004–0.412$.
