摘要

The principal refractive indices and the thermal refractive index coefficients for Be3Al2Si6O18crystal doped with 1.01wt% Cr2O3 have been accurately measured by the auto-collimation method at wavelengths of 0.488, 0.53975, 1.064, 1.0795 and 1.3414μm, and temperatures of 308.2, 328.6, 359.1 and 395.4 K respectively. Based on the measured results of principal indices of 0.488, 0.6328, 1.0795 and 1.3414μm, the Sellmeier's equations and the thermal refractive index coefficients have been obtained,and the result has been proven to be accurate by e. rror analysis.
