A Sellmeier equation for the extraordinary index of congruent lithium niobate is derived. The source data for the fit contain previously published data [Opt.Commun.17, 322 (1996); erratum 20, 188 (1997); J.Appl.Phys. 45, 3688 (1974)] and new measured tuning data for an optical parametric oscillator using periodically poled lithium niobate. Phase-matching predictions are accurate for temperatures between room temperature and 250 degrees C and wavelengths ranging from 0.4 to 5 mum .
推导了同成分铌酸锂异常折射率的Sellmeier方程。用于拟合的源数据包含先前发表的数据[《光学通讯》17, 322 (1996); 勘误20, 188 (1997); 《应用物理杂志》45, 3688 (1974)]以及使用周期性极化铌酸锂的光学参量振荡器的新测量调谐数据。相位匹配预测对于室温至250摄氏度之间的温度以及0.4至5微米范围内的波长是准确的。
