Abstract
The paper describes a self-consistent two-dimensional nonstationary model of the ineraction between a CO2-laser beam and a low-temperature surface plasma. Account is taken of gasdynamic and refraction processes, of laser-emission absorption, and of the real equation of state. Principal attention is paid to a description of a quick discrete vector algorithm for the solution of the geometric-optics equations. The propagation and decay of an optical-detonation wave in a focused laser beam is investigated for the first time with the aid of a self-consistent numerical model.
