Abstract

Simple equations of laser‐induced plasma shock wave motion in air are studied, based on the point blast theory. The theoretical models of the shock wave front evolution characterize two stages of shock wave propagation: the initial formation stage and the free attenuation stage. Due considerations of the boundary conditions, the validity range of the attenuation equation is larger than the one of the t^2/5^ law of the self‐similar solution. Furthermore, the theoretical results are in good agreement with the experimental data and nuclear explosion results. Β© 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 38: 75–79, 2003

The shock wave plasma induced by the bombardment of laser light coming from a commercial TEA CO2 laser has been used for the direct elemental analysis of solid samples. By using standard low-alloy steel samples, it is demonstrated that there is a linear relationship between the Cr content and the em
