The principal refractive indices of crystal CsB3O5 (CBO) at the wavelengths of 0.266, 0.355, 0.532, 0.473, 0.633, 1.064, and 1.338 μm are accurately measured by using the autocollimation method within the temperature range from 40°C to 190°C. We derive and report equations of thermal refractive index coefficients as a function of wavelength that could be used to calculate the principal thermal refractive indices at different wavelengths. Sellmeier equations at different temperatures were derived and used to calculate the phase-matching angles for the third-harmonic generation and the fourth-harmonic generation of CBO crystal at different temperatures.
利用自准直法在 40°C 至 190°C 的温度范围内精确测量了晶体 CsB3O5（CBO）在 0.266、0.355、0.532、0.473、0.633、1.064 和 1.338μm 波长处的主折射率。我们推导出并报告了热折射率系数随波长变化的方程，这些方程可用于计算不同波长下的主折射率。推导出不同温度下的Sellmeier 方程，并用于计算不同温度下 CBO 晶体三次谐波和四次谐波产生的相位匹配角。
