分析了ＫＮｂＯ３晶体的电光性质，利用电光张量系数γ３３加工成电光偏转器，偏转梯度电场由四个柱面电极产生。实验结果表明，在结构参数、通光口径及其它条件均等同的情况下，该器件的基本品质因子约是ＬｉＮｂＯ３电光偏转器的２倍。
The electro-optic properties of KNbO3 crystal were analyzed and processed into electro-optic deflector by electro-optic tensor coefficient γ33. The deflection gradient electric field was generated by four cylindrical electrodes. The experimental results show that the basic quality factor of the device is about twice that of LiNbO3 electro-optic deflector under the same structural parameters, clear aperture and other conditions.
