| 摘 要： | 设计了新ＫＴＰ电光偏转器，当通光口径Ｄ＝４ｍｍ，长度Ｌ＝４０ｍｍ时，其时间分辨率为１８０ｐｓ，从而可获得最窄宽度为４００ｐｓ的整形激光脉冲，而相同结构的ＬｉＮｂＯ３电光偏转器最窄只可获得宽度为８３０ｐｓ的整形激光脉冲，分析了电光偏转器设计中影响其性能指标的因素，指出利用恒温炉装置可消除激光脉冲在传播过程中的波面畸变。

| Abstract: | A novel KTP electro optic deflector with diameter D=4 mm, length L=40 mm, is designed. Compared with the same size LiNbO 3 deflector, the temporal resolution of KTP deflector is 180 ps, while LiNbO 3 deflector is 414 ps. The shaped laser pulse with the least width of 400 ps of KTP deflector and 830 ps for LiNbO 3 can be obtained respectively. Factors affect the property of electro optic defector are analyzed. Using a temperature controlled oven, the wave front distortion in laser pulse propagation can be eliminated. |

| Keywords: | KTP electro optic deflector quality factor temperature compensation temporal resolution. |
