Ultrafast Laser Investigation of a Solid-State Explosion

Abstract

The response of solids composed of large molecules, to the rapid deposition of a large amount of energy was studied experimentally and theoretically. Laser equipment capable of inducing a solid state explosion, and studying, via ultrafast microscopy, and a variety of nonlinear optical techniques, was constructed, and used to investigate the behavior of a variety of solid materials on times ranging from 2 picoseconds (trillionths of a second) to seconds. The theory of statistical mechanics, and the methods of super- computer simulations was used to analyze the results of the experiments, and to make predictions about planned experiments where laser driven shock waves are used to induce chemical reactions in energetic solids.
