Title: Laser-driven flat plate impacts to 100 GPA with sub-nanosecond pulse duration and resolution for material property studies

Abstract

Miniature laser-driven flat plates (<1-mm diam {times} 0.5--10{mu}m thick, typical) of aluminum, cooper, tungsten, and other materials are accelerated to {le}5 km/s. These miniature plates are used to generate one-dimensional shock waves in solids, liquids, and crystals. Dynamic measurements of spall strength at strain rates {le}10{sup 7} s{sup {minus}1}, elastic-plastic shock wave profiles in 10-{mu}m-thick targets, shocked free-surface acceleration of 10{sup 12} m/s{sup 2}, and laser-driven plate launch accelerations of 10{sup 10} m/s{sup 2} are routinely obtained. The small size of the sample of and projectile mass permits recovery of targets without additional unintended damage or energy deposited into the test specimen. These miniature plates can be launched with conventional 1-J laboratory lasers. 10 refs., 5 figs.
