Paper Abstract

The motion of both Lennard-Jones solids and metals induced by ultrashort laser irradiation near the ablation threshold is investigated by molecular dynamics simulation. The universality of the ablation threshold fluence with respect to the cohesion energy of solids irradiated by femtosecond laser pulses is demonstrated for Lennard-Jones solid and metals simulated by many-body EAM potentials.
