Modelling of melting and resolidification of thin metal film subjected to ultrafast laser pulse using the two-temperature model

The heating of thin metal film subjected to the ultrafast laser pulse is analyzed. The thermal processes occurring in the domain considered are described using the hyperbolic two-temperature model supplemented by the procedure of melting and resolidification modelling. The problem is solved by means of the implicit scheme of the finite difference method. The examples of computations for different laser intensities and characteristic times of laser pulse are presented.
