Particle velocity measurements in laser irradiated foils using ORVIS

OSTI ID:5634153
Aluminum foils from 2- to 200-..mu..m thick have been subjected to a Nd:YAG laser pulse of low irradiance (10/sup 9/ W/cm/sup 2/, approx. 10 ns pulse) to produce laser-driven shocks in the foils. The particle velocity history of the foil side opposite the laser deposition was monitored with nanosecond resolution by a velocity interferometer system called ORVIS. These histories indicate a shock reverberation process accelerates the foil. Peak foil velocities can be adequately calculated using a ricket propulsion model developed from experiments at much higher irradiances. A velocity of 1 km/s was developed in a 2-..mu..m-thick free foil in a time of 50 ns. Water-confined foils attained peak particle velocities about three times higher than those of free foils.
