摘要
根据Er：Sr3Gd（BO3），（Er：SGB）的透过率曲线粗略估计了该晶体的折射率，再利用自准直法，精确测量了30～170℃范围内，0．4880μm、0．6328μm、1．0640μm、1．338μm等波长下Er：SGB晶体的主轴折射率，得到Sellmeier方程并计算了1．319μm下Er：SGB晶体的主轴折射率，与实验测量的结果进行比较，两者的差异不大于2×10^-4，处在测量误差的范围内，验证了实验结果的可靠性。
The refractive indices of Er： Sr3Gd （BO3 ）3 （Er-SGB ） crystal were calculated base on its transmission profile, and the precise values at the wavelengths of 0. 4880, 0. 6328, 1. 0640 and 1. 338μm in the range from 30℃ to 170℃ were measured by auto-collimation method. The Sellmeirequations at different temperatures were obtained. The refractive indices of 1. 319μm at different temperatures were calculated by the Sellmeir-equations and compared with the measured values in order to check their reliability. As a result, the difference between the calculated results and the measured results is less than 2 × 10 ^-4.
