Sellmeier and thermo-optic dispersion formulas for β-BaB_2O_4 (revisited)

摘要

This paper reports the high-accuracy Sellmeier and thermo-optic dispersion formulas for β-BaB_2O_4 (β-BBO) that provide the excellent reproduction of our data for second-harmonic generation (SHG) and sum-frequency generation (SFG) down to 0.2048 and 0.1925μm as well as the optical parametric oscillator (OPO) tuning points up to 3.2μm, and the temperature-dependent phase-matching angles for SHG and SFG that we have measured in the 0.193-0.6420μm range as well as the recent data for SFG at 0.1934μm.
