Large-scale atomistic simulations of the structural transformations in short pulse laser processing of metals
Abstract
The mechanisms of material ejection and surface modification in short-pulse laser processing of metal targets are investigated in large-scale atomistic simulations performed with a model that combines the classical molecular dynamic method with a continuum description of the laser excitation of conduction band electrons, electron-phonon coupling and electron heat conduction. The results of the simulations reveal a complex picture of highly non-equilibrium processes responsible for material modification and/or ejection in response to the fast laser energy deposition.
