Paper Abstract

Experimental studies on laser driven high-speed metallic flyers have been carried out wiht a moderate Q-switched YAG laser whose output is 1J and pulse FWHM of 10 ns. An aluminum film of thickness 5.5 micrometers was accelerated to a speed about 7 km/s. The experiments on initiation of explosives and spallation of metals were performed using laser driven flyer. A numerical model is explored here for a description of vaporization, ablation and ionization during the laser irradiation and can give reasonable results compared with the experiments.
