The numerical study of the behavior of a gas plume and a nano-aggregates created during the short pulse laser ablation is studied by the method of molecular dynamics. During the evolution of a nanoparticle, two phenomena coexist: the city (or aggregation) and evaporation. The threshold temperature of the nanoparticle from which evaporation is dominant is determined. The presence of the plume gas modifies this behavior. On the other hand, the condensation of this gas is a significant parameter in the continuation of this study
