Temperature field of the irradiated material in the laser-induced damage

The use of powerful pulse lasers in various areas of science and technology requires an understanding of the physical mechanisms of laser-induced damage to the irradiated substance. In this paper, we consider the numerical solution of the one-dimensional non-stationary heat equation. The developed algorithm of the solution and the software, created with this application using a specialized application software package, allowed one to analyze the dynamics of a number of parameters of laser ablation destruction. It is possible take into account the differences and make calculations, based on the developed computer program for parameters, which can depend on time and coordinates in an arbitrary way. As the most significant application, one can point out the approximations of the solutions obtained for the sub-threshold radiation conditions.
