Thresholds for front-side ablation and rear-side spallation of metal foil irradiated by femtosecond laser pulse
Source abstract
Abstract
The mechanical action of laser exposure on a foil may result in the ablation of irradiated front layer and the rear-side spallation. The dynamics of an Al foil is studied by means of two-temperature (2T) hydrodynamics and molecular dynamics (MD). It is found that the rear-side spallation threshold Fs exceeds the front-side ablation threshold Fa. We propose to extend the common approach in laser-matter experiments by pump–probe measuring of the rear-side displacement.
