介绍了脉冲功率技术在离子准分子、准分子和软X射线激光研究中的应用情况。给出了三种激光产生对泵浦源电学参数的要求,并给出实现这些电学参数的实验装置以及实验装置的性能指标。在软X射线激光研究方面,利用10级Marx发生器和Blumlein传输线,建立了最高电流峰值40 kA,前沿为26.6 ns的毛细管放电装置,并实现了46.9 nm激光输出。建立了输出电压600 kV、输出电流20 kA的电子束装置,并作为泵浦源实现了离子准分子光腔效应。为了泵浦S2准分子,采用横向放电方式和低电感放电回路,实现了电压脉冲宽度为29.2 ns的窄脉冲放电。

The high power pulse technology, which is used in the ionic excimer, excimer and soft X-ray lasers, is introduced. The electrical parameters required by the three types of lasers are given respectively. In order to obtain soft X-ray laser, ten-stage Marx generator and Blumlein transmission line are used to build the capillary discharge device with maximum current of 40 kA and rise-time of 26.6 ns. The soft X-ray laser is observed with the device. The electron beam device with voltage of 600 kV and current of 20 kA is used to pump the ionic excimer and the resonator effects are obtained. The narrow voltage pulse of 29.2 ns is realized to excite S2 excimer.
