摘要
实验研制了基于磁脉冲压缩系统的脉冲气体激光器用固态高压开关,实验中通过调节复位电流大小,负载电阻大小等相关参数实现了磁压缩开关输出效率达到最大值。经两级磁开关压缩后脉宽约压缩为原来的5%。压缩后脉冲上升时间约为180 ns,幅值约为16 kV。其中第一级磁压缩效率为89.2%,第二级磁压缩效率达到97.7%,总的压缩效率达到87.2%。接激光器后测得输出激光脉冲能量约为20 mJ,输出激光脉冲半高宽约为85 ns。
A solid-state high voltage switch for pulsed gas laser based on magnetic pulse compression system was developed in the experiment.The output efficiency of the magnetic compression switch was maximized by adjusting the reset current and load resistance.After being compressed by two-stage magnetic switch,the pulse width was about 5%of the original.The rising time after compression was about 180 ns,and the amplitude was about 16 kV.The first-stage magnetic compression efficiency was 89.2%,the second-stage magnetic compression efficiency was 97.7%,and the total compression efficiency reached 87.2%.After receiving the laser,the measured output laser pulse energy was about 20 mJ,the output laser pulse half-height and width were about 85 ns.
