Modeling of Free Electron Laser Ablation

Abstract

A novel breathing sphere model was developed in order to make microscopic molecular dynamics simulations tractable for laser ablation. The results of the simulations have allowed us to distinguish between desorption and ablation, predict velocity distributions of ablated particles, predict the fluence dependence of the ablation yield, explain the forward peaked angular distributions and predict the acoustic pressure wave characteristics. Numerous favorable comparisons with experimental data have been made.
