摘要
The principal refractive indices of Ca9La(VO4)(7) crystal for wavelengths of 0.488, 0.6328, 1.064 and 1.338 mu m under the temperature range from 30 degrees C to 170 degrees C were measured by auto-collimation method. The Sellmeir-equations of Ca9La(VO4)(7) crystal at different temperatures have been obtained based on the experimental data. and the refractive indices of some wavelengths in different temperatures are calculated by the Sellmeir-equations and compared with the corresponding measured values in order to check their reliability. As a result, the difference between the calculated results and the measured results is not more than 1 x 10(-4). The theoretical PM (phase matching) angles of SHG (second harmonic generation) built on the experimental refractive indices are also given.
