AgGaS2 has been found to be 90° phase matchable at 192 °C for sum-frequency mixing between the output of the KTP parametric oscillator at 3.2627 µm and its pump source at 1.0642 µm. The thermo-optic dispersion formula that can be used for good reproduction of the temperature-dependent phase-matching conditions thus far reported in the literature as well as our new data for second-harmonic generation of a CO2 laser and its harmonics at 1.7652–5.2955 µm is presented.
