在40℃~ 190℃的温度范围内，采用自准直法精确测量了CsB3O5 （CBO）晶体0.266、0.355、0.532、0.473、0.633、1.064和1.338 μm波长处的主折射率。我们推导并报道了热折射率系数随波长的函数方程，可用于计算不同波长处的主热折射率。推导了不同温度下的Sellmeier方程，计算了CBO晶体在不同温度下的三次谐波和四次谐波相匹配角。
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.
