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.
Keywords: laser-induced damage; laser ablation; method of moments. |
