介绍了通光口径为300mm×300mm的等离子体电极电光开关驱动电源系统原理.该系统能产生时序上严格关联的两路幅值3kV、脉宽为500ms预电离高压脉冲;两路电压幅值为7kV、电流峰值为2kA的阻尼大电流、低抖动主放电脉冲;一路幅值为12kV、脉宽500ns低抖动矩形高压开关脉冲.这五路高压脉冲通过3根同轴电缆加载到充有惰性气体的纵向普克尔盒两边的阴阳电极上,对激光形成等离子体电极电光开关.

This paper describes the principle of plasma electro-optical switch driving system. The system use plasma electro-optical switch system in high power ICF drivers based on large aperture size (for example, 300mm×300mm) multipass amplifier array scheme. The systems can product strict sequential correlated five high-voltage strong-current pulses. These pulses are loaded on longitudinal Pockels cell full of inert gas through three coaxial cables. As the electro-optical switch with plasma electrodes has unique advantage of high efficient, fast for on/off, high precision, large aperture size and high laser damage threshold, it has become an ideal switch system in new generation of ultra-high power laser system.
