摘要
采用光偏转法研究气体中准分子激光与石墨和铜相互作用产生等离子体羽的特性．用空间和时间分辨的光偏转信号分析了等离子体羽的漂移速度和膨胀速度，并从光偏转信号中测得了物质波前面的激波速度．
The evolution of laser generated plume in ambient gates was investigated usinglaser beam deflection technique. A XeCl excimer laser was employed to initiate thevaporization of graphite and copper targets. The information drawn from the sPatiallyand temporally resolved deflection signals makes us to estimate the plume driftingvelocities and expansion-velocities at different sarge of evolution. Also, the deflectionsignals showed that drifting of the laser blow-off material developed a shock wave whichmoves ahead of the material wave.
