Abstract

The dynamics of electronic and lattice excitation and material removal in ultrafast laser ablation of dielectrics, semiconductors, and metals was studied experimentally and theoretically. Dielectrics were strongly charged at the surface on the femtosecond time scale and underwent an impulsive Coulomb explosion. The calculations were found in good agreement with femtosecond pump-probe studies and measurements of velocity distributions of emitted ions.
