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. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 38: 75–79, 2003
