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 microm and for temperatures of 30-200 degrees 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.
我们给出了化学计量比钽酸锂折射率的温度相关塞尔迈耶方程。对于0.39 - 4.1微米的波长范围以及30 - 200摄氏度的温度，非常折射率是基于先前发表的数据[《日本应用物理杂志》41, 465 (2002)]以及从准相位匹配（QPM）共振得出的测量数据。我们使用所获得的新塞尔迈耶系数来计算基于周期极化化学计量比钽酸锂且泵浦波长为1064纳米的光学参量振荡器（OPO）的QPM波长。OPO的测量波长与我们的预测结果吻合良好。
