Résumé

The modification of the Anisimov–Lukyanchuk model to define the processes of dynamic condensation of Zel'dovich–Reiser for vapor-plasma jets formed during laser ablation of a silver target by intensive nanosecond pulses of optical radiation in a normal atmosphere is described. The initial stage of development of ablative silver jet with a high degree of accuracy corresponds to the theory of dynamic condensation of the Zeldovich–Raiser, and at the stage of disintegration of the ablation torch, it is necessary to take into account an additional mechanism of droplet formation – adhesion of the “nuclear”.
