Molecular dynamics study of the mechanisms of gold ablation under the influence of ultrashort laser pulses using different potentials
Abstract:
Using simulation with a continuum-atomistic model, a study of ablation under the action of an ultrashort laser pulse on a metal (Au) was carried out. Three regimes of ablation were studied: supercritical expansion, phase explosion, and mechanical spallation. The results for two EAM potentials of gold are compared. A graph of the dependence of the amount of removed substance on the fluence of laser radiation for two potentials is constructed, followed by comparison with experimental data.
