Abstract

This paper reports on the new thermo-optic dispersion formula for AgGaSe₂ that provides a good reproduction of the temperature-dependent phase-matching conditions for second-harmonic generation (SHG) and sum-frequency generation (SFG) of a CO₂ laser and a Nd:YAG laser-pumped KTP optical parametric oscillator (OPO) in the 1.5558 - 10.5910 μm range as well as those for difference-frequency generation (DFG) between the signal and idler outputs of a Nd:YAG laserpumped 90° phase-matched CsTiOAsO₄OPO at λ_i = 7.5190μm when combined with the modified Sellmeier equations of the present authors [E. Takaoka and K. Kato, Appl. Opt., 37, 561-564 (1998)].
