Thermal processes in domain of thin metal film subjected to a strong laser pulse are discussed. The heating of domain considered causes

the melting and next (after the end of beam impact) the resolidification of metal superficial layer. The laser action (a time dependent belltype

function) is taken into account by the introduction of internal heat source in the energy equation describing the heat transfer in domain

of metal film. Taking into account the extremely short duration, extreme temperature gradients and very small geometrical dimensions of

the domain considered, the mathematical model of the process is based on the dual phase lag equation supplemented by the suitable

boundary-initial conditions. To model the phase transitions the artificial mushy zone is introduced. At the stage of numerical modeling the

Control Volume Method is used. The examples of computations are also presented.
