This paper reports high-accuracy Sellmeier and thermo-optic dispersion formulas for GaSe that provide excellent reproduction of the phase-matching conditions for second-, third-, and fourth- harmonic generation of CO 2 laser radiation at 10.5910 μm in the 20°C–200°C range as well as the data points of Feng et al. [Opt. Express 16, 9978 (2008)] for second-harmonic generation of CO 2 laser radiation at 9.5862 μm and an Er 3 + : YSGG laser at 2.7960 μm in the 165 ° C 230 ° C range.
