RÉSUMÉ

An axisymmetric microdomain subjected to the ultrashort laser pulse is considered. The two-temperature hyperbolic model, together with the isothermal solid–liquid and liquid–vapor phase changes, is presented. This model consists of six highly nonlinear equations. These equations describe both the electrons and lattice heat fluxes in the radial and axial directions as well as the electrons and lattice temperatures. To solve these equations supplemented by appropriate boundary and initial conditions, the finite difference method with staggered grid is proposed. The algorithm contains the procedures which take into account the phase changes occurring at the constant temperatures. In the final part of the paper the results of computations are presented.
