Paper Abstract

Measurements of laser induced shock pressures are made using polyvenyliden fluoride (PVDF) gauges which were stoke on the back of 0.04 and 0.2 mm thick targets, covered with polymethyl methacrylate (PMMA) windows and irradiated by laser pulses of 33 ns duraction, at incident intensity between 108 and 109 W/cm2. The integral shock profiles on the front face of PVDF and the decay of laser induced shocks were obtained by measuring the shock pressures in aluminum targets with different thickness. The experimental results are analyzed by the way of computer simulations to illustrate the decay of the shock peak pressures and the shock profile evolution.
