| Abstract: | 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. |
