Abstract

The theory of plasma ablation by laser irradiation of a solid target is considered when thermal conduction is weak and the absorption is dominated by inverse bremsstrahlung (the self-regulating model). Analytic solutions are identified to treat both steady and time-dependent flows in limiting cases. The intermediate behaviour is explored by numerical modelling. The models are presented for planar, cylindrical and spherical geometries with both tight and weak focused beams. A brief investigation of the applicability of analytic models to the heating of thin foil systems is also presented.
