摘要We propose new coefficients for the ellmeier equations of 1.0mol % Mg-doped stoichiometric LiTaO3. The extraordinary refractive indices for the wavelength range 0.5-4.0μm and for temperature 30-170°C 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 1064nm. The corrected refractive indices are in good agreement with our experimental data obtained from QPM OPO and SHG pumped at 1064μm at different temperatures.
