Abstract

Theoretical consideration of the ablation of laser heated metal target based on two-temperature hydrodynamic calculation is performed for aluminum and gold targets. Concurrent with the hydrodynamic calculation the molecular dynamics simulation of the ablation was carried out in the case of aluminum. The initial state of matter for the molecular dynamics is taken as a final state of hydrodynamic calculation. Molecular dynamics simulation is extended to cover late stages of the evolution of two-phase foam placed between the crater and spalled cupola. Theoretical results are in a good agreement with the experimental data obtained by the microinterferometer diagnostics of the femtosecond laser ablation both for aluminum and gold.
