Paper 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 CsTiOAsO4 OPO at λi = 7.5190μm when combined with the modified Sellmeier equations of the present authors [E. Takaoka and K. Kato, Appl. Opt., 37, 561-564 (1998)].
