Аннотация
A continuum-atomistic model that describes nonequilibrium thermal, hydrodynamic, and electronic processes in metals that occur under the action of ultrashort (fs, ps) laser radiation has been developed. A detailed study of two mechanisms of ultrashort laser ablation of Cu was carried out: fast - Coulomb, determined by Coulomb forces, and slow - thermal, realized in the unloading wave after the end of the laser pulse. Modeling showed that the excess nonequilibrium pressure of collectivized electrons plays a leading role in the formation of a strong electric field at the metal-vacuum interface. This effect can be taken as the basis for the Coulomb explosion in metals. The main feature of the work is the widespread use of modern visualization tools for processing and presenting simulation results.
