The structure of an axisymmetrical nonstationary wave of laser emission absorption in a transparent dielectric
Abstract
The formation and development of waves of laser emission absorption in a condensed medium is investigated numerically for power densities of incident radiation of 3 MW/sq cm. A solution is presented for two-dimensional heat conduction equations with strongly nonlinear coefficients and heat sources which model the absorption of an external source in terms of geometrical optics. Consideration is given to the complex structure of temperature fields consisting of one main and several secondary waves propagating at different velocities toward the laser radiation.
