Abstract
The thermo-optic constants of AgGaSe2 have been measured at 2.052, 3.3913, 5.2955, and 10.5910 μm. These results combined with values reported in the literature were used to construct the thermo-optic dispersion formula that correctly reproduces the temperature-dependent phase-matching conditions for second-harmonic generation and sum-frequency generation of a CO2 laser as well as the thermally induced lensing effects for the 2.05-μm pumped parametric oscillators.
