摘　　要：介绍用两个相同的电光偏转器相应的电极并联连接后,激光脉冲光束依次通过它们进行偏转扫描的削波整形原理.由实验测出用两个电光偏转器并联比用单个对激光脉冲扫描光线更长,在同样的狭缝宽度下削出更窄的激光脉冲,提高了输出激光脉冲幅度的稳定性,幅度起伏RMS的精度提高了约33.3%,实验结果与理论基本一致.虽还没有达到理论分析预期的效果,但也说明电光偏转器偏转能力还有进一步挖掘的潜力,用电光偏转器进行激光脉冲稳定性的实验研究,在惯性约束核聚变、激光脉冲削波、整形等方面有广泛的应用前景.The article studies clipped wave and shaping principles of leser pulse beam through two electro-optical deflectors in parallel. The experiment shows that scanning light is longer by itself than the single one, and clipped wave of laser pulse is more narrow under same seam width. The stability of amplitude of output laser pulse is raised,and the precision of amplitude fluctuations RMS is increased by 33.3 %. The experimental result is in accordance with the theory. There are the potential of the deflective power of electro-optical deflctor. The study has broad prospects of application in nuclear fusion by inertia restraint, clipped wave and the shaping of laser pulse.
