The abnormal phenomena in the transmitted light passing through a-LiIO_3 single crystals under the application of a DC field parallel to the c-axis have been further investigated by means of the direct projection method, the optical Fourier transfor-mation method and the Schlieren method. The change in the spacial frequency spectrum of a z-cut crystal plate with the increase of the applied field intensity was examined. It was observed that the diffraction efficiency of the transmitted light shows a linear dependence on the applied voltage, but is independent of the polariza-tion of the incident light. It was also found that the light polarization is not changed by the action of the DC field and the effect of absorption is negligible. The relaxa-tion process of the change in diffraction efficiency with time was recorded quantita-tively. A tentative explanation of these phenomena has been given.

The“half-wave voltage”usually was used to assess the modulated property of different electrooptic crystals. Beside this factor, we must take into account the extinction ratio(defined as the ratio of the maximum to the minimum transmitted light intensity). The size of the extinction ratio depends not only on the optical homogeneity of the crystal, but also on the radius of the laser beam.

The“half-wave voltage”usually was used to assess the modulated property of different electrooptic crystals. Beside this factor, we must take into account the extinction ratio(defined as the ratio of the maximum to the minimum transmitted light intensity). The size of the extinction ratio depends not only on the optical homogeneity of the crystal, but also on the radius of the laser beam. Therefore, we often used the fluctuation of the nature birefringence to show the optical inhomogeneity of the crystal. In this paper, an automatic scaning measurement method which has more advantages than the extinction angle method was described. The equipment also was used to investigate dynamic and static extinction ratio, influences of electric domains on the optical homogeneity and electrooptic effect in LNbo_3 crystals. and to obtain the signal of the phase transition of LiNbo_3 crystal near 75℃. Finally, we discussed the measured results.

调制晶体的性能好坏,通常是由半波电压和消光比这二个量来表征的。而消光比往往与晶体的光学均匀性有关。本文介绍了一种可用于测量晶体的双折射率梯度、消光比、半波电压以及双折射率随温度变化的自动扫描装置及工作原理。该方法和其他方法相比具有测量速度快,重复性好,及误差小等优点,并可以从扫描曲线上直接定性地判别晶体的光学性能的好坏,文章最后还做了双折射率梯度及消光比的测量,并对实验结果进行了讨论。
