Abstract

We present a temperature-dependent Sellmeier equation for congruent and stoichiometric LiTaO₃. The refractive indices in the range of 0.39-4.1 μm were determined by scanning the pump lasers wavelength and finding the QPM second harmonic wavelength for a series of period-temperature pairs, and from QPM OPO measurements. The obtained new Sellmeier coefficients were used to calculate the QPM wavelengths of the idler and signal for a PPSLT OPO pumped at 1064 nm. An OPO based on PPSLT was demonstrated. The idler-tuning range was 4.1828-3.9898 μm for temperatures of 40-200 °C. The measured wavelengths were in good agreement with our predictions.
