多通道开关是获得高气压下大体积均匀激光放电的关键技术之一,本文对上述激光放电回路进行了理论分析。根据通道开关在不同气压下的自击穿电压特性,用计算机编码计算了不同电压和重复率下的放电特性和对激光输出的影响,计算结果能与实验很好地符合。

Rail gap is one of the most important technology to obtain large volume uniform discharge at high gas pressure. In this paper, a pulsed laser discharge circuit w’th a rail gap was analyzed theoretically. According to the self breakdown, voltages of the rail gap at different gas pressures, a computer code was used to calculate the discharge characteristics and laser output for different discharge voltages and repetition rates. The calculated results are in good agreement with the experimental data.
