测量了7.5mol.%的玻璃的主折射率和热折射率系数用自准直法测量了Nb：KTiOPO（4）晶体从室温到143 ℃的0.53975，0.6328，1.0795和1.3414 μ m波长范围内的光场。得到了室温下的Sellmeier方程，并利用该方程计算了1.0642和1.0795 μ m的最佳相位匹配角。计算值与实验值吻合较好。
The principal refractive indices and the thermal refractive-index coefficients of 7.5-mol.% Nb:KTiOPO(4) crystal were measured by autocollimation for wavelengths of 0.53975, 0.6328, 1.0795, and 1.3414 microm from room temperature to 143 degrees C. The Sellmeier equations at room temperature were obtained and used to calculate the optimal phase-matched angles for 1.0642 and 1.0795 microm. The calculated and experimental values are in good agreement.
