Abstract
A high-irradiance short pulsed laser was used to generate hemispherica l shock waves in planar targets. A linear relationship was obtained be tween the laser energy for threshold spall conditions (E(L)) and the c ubic target thickness (d): E(L) = 45.3d3 + 4.9, where E(L) is in J and d is in mm. It is found that the laser-induced ablation pressure deca ys with the distance to a power slightly greater than 2.
