摘要
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。
In this paper, the electrooptical properties of a KNbO3 single crystal was studied. A KNbO3 deflector with four cylindrical electrodes, which utilizes the coefficient γ33 of the EO tensor, was made. Results of the experiment indicated that the fundamental figure of merit of the KNbO3 deflector was about twice that of the LiNbO3 crystal with equal structural parameters, aperture and length.
