In this study, simulation of femtosecond laser interaction with aluminum has been investigated using the combined two –temperature model and molecular dynamics. The two-temperature model describes the evolution of the electron temperature and molecular dynamics is used to describe phase transformations occurring under highly non-equilibrium condition induced by ultrashort laser irradiation. These two subsystem are combined using a coupling term. The simulation is performed for an absorbed fluence of 200 and the evolution of electron and lattice temperatures, energy changes and phase transformations are presented.
