Abstract

Cumulative effects in gases accompanying hydrodynamic motion due to powerful laser energy deposition deal with the problems of high-speed jet generation and plasma heating. In the present paper, on the basis of experimental simulation and theoretical analysis we investigate the behavior of a cumulative ring shock wave near the axis of symmetry. Such a shock wave arises after the energy deposition into the volume of a gas having the form of a thin torus.
