Abstract

The paper reviews recent results on modeling a viscous liquid flow driven by ablation pressure. Based on the analysis of the Navier-Stokes equation various strongly different manifestations of this phenomenon are explained. These are: (i) a "clean" laser ablation, when laser spot has a clean sharp spot border, free from a re-solidified melt dross; (ii) a new form of material removal in laser ablation - expulsion on a poly(methyl methacrylate) target of long (up to 1 mm) nanofibers with a radius about 150-200 nm to the exterior of the spot under the action of a single pulse of KrF excimer laser; and (iii) a new way of laser surface nanostructuring - the formation of a surface foam having a structure of micro-pores interconnected with nanofilaments of diameters about 100 nm as a result of single pulse KrF laser irradiation of biopolymer films.
