【摘要】 基于快放电(毫微秒)XeCl激光器电极两端电压和电流的精确测量和计算机分析,给出高气压(3—8大气压力)激光放电等离子体的动态阻抗特性。在几毫微秒内,阻抗降到欧姆量级。研究了放电峰值电流和平均阻抗与充电电压和气体压力的关系。结果显示,放电等离子体阻抗与传输线阻抗精确匹配并不是十分重要和实际的。更多还原

【Abstract】 Based on accurate measurements of voltage and current between electrodes of a fast discharge XeCl laser, together with computer analyses, the kinetic impedance of gaseous mixture at high pressure of 3 to 8 atmospheres under discharge was obtained. The high impedance droped down to a fraction of ohm within several nanoseconds. The discharge peak currents and corresponding impedances of laser cavity at various charge voltages and gas pressures were studied. The results show that it is impractical and unimportant to match precisely the impedances of discharge plasma and of transmission line.更多还原
