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.
