Abstract

Ultrashort-pulse laser irradiation may melt the target and, at higher intensities, lead to ablation. The state of the material shortly after irradiation is characterized by high temperatures and pressures (both tensile and compressive). In addition, the material may not yet be in thermal equilibrium. Molecular dynamics simulation is well suited to model the state of matter under these conditions. We give several examples of how molecular dynamics simulations have contributed to understanding the ablation phenomena after ultrashort-pulse laser irradiation.
