We propose new coefficients for the Sellmeier equations of 1.0mol% Mg-doped stoichiometric LiTaO3. The extraordinary refractive indices for the wavelength range 0.5-4.0#m and for temperature 30-170℃ are based on measured data derived from quasi-phase-matched (QPM) optical parametric oscillator (OPO) and second-harmonic generation (SHG) based on periodically poled Mg-doped stoichiometric LiTaO3 with a pump wavelength of 1064 nm. The corrected refractive indices are in good agreement with our experimental data obtained from QPM OPO and SHG pumped at 1064 μm at different temperatures.
