摘　　要：利用自准直法,在30℃到170℃温度范围内分别测量0.4880μm、0.6328μm、1.0640μm、1.3414μm等波长下BiB3O6(BIBO)晶体的主轴折射率·得到不同温度下的Sellmeier方程及各主轴折射率的温度系数.计算了1.0795μm下BIBO晶体的的主轴折射率.与实验测量的结果进行比较,两者的差异不大于2×10-4·The principal refractive indices of BIBO crystal for wavelengths of 0. 4880, 0. 6328, 1. 0640 and 1. 3414μm under the temperature range from 30℃ to 170℃ were measured by auto-collimation method. The Sellmeir-equations at different temperatures and thermal coefficients of refractive indices have been obtained. In order to check their reliability, the refractive indices of 1. 0795μm in different temperatures are calculated by the Sellmeir-equation and then compared with the measured values. As a result, the difference between the calculated results and the measured results is less than 2 ×10^-4.
