A BRIEF DESCRIPTION OF THE LASER-INDUCED SURFACE BREAKDOWN OF REFRACTORY-METALS .2. GENERATION OF BASINS OF LOCAL SURFACE DYNAMICS

Inhomogeneity of laser-driven technological processes, caused either b y beam inhomogeneity or surface inhomogeneity is considered. inhomogen eity is induced through the inhomogeneous temperature and the pressure fields on the material surface, thus dividing it into domains of soli d response, liquid response and the vapor/liquid response regime. The set of the gradient pairs Delta T-perpendicular to,parallel to(+,-) De lta P-perpendicular to,parallel to(+,-) give rise to 16 possible subdo mains (basins), everyone of which is an origin of characteristic dynam ics. Depending on the dominant gradient pair combination, a number of physical phenomena are derived. They may simultaneously appear in vari ous basins of the interaction space, generated in the single or the mu ltishot treatment.
