Abstract

We present a temperature-dependent Sellmeier equation for the refractive index of stoichiometric LiTaO₃. The extraordinary refractive index, for the range 0.39-4.1 μm and for temperatures of 30-200 °C, are based on previously published data [Jpn. J. Appl. Phys. 41, 465 (2002)] and on measured data derived from quasi-phase-matched (QPM) resonances. We used the new Sellmeier coefficients that we obtained to calculate the QPM wavelengths for an optical parametric oscillator (OPO) based on periodically poled stoichiometric LiTaO₃ pumped at 1064 nm. The measured wavelengths of the OPO were in good agreement with our predictions.
