Abstract
The results of the theoretical analysis and computer simulations of the set of phenomena arising at high intensity subpicosecond laser pulse action on a solid target surface are presented. Surface damage processes are discussed including plasma creation, dynamics of the laser pulse interaction with the induced plasma layer, self- focusing and spatial instabilities of the laser beam. In particular a possibility of pulse energy density enhancement in plasma due to the self-focusing, self-organization and forging of dynamical structures and spatial instabilities are investigated. These structures are responsible for the creating of superstrong magnetic fields and appearance of ultrafast electrons with energy up to 50 MeV. Our researches are initiated by the latest experimental achievements and serve for the purposes of their theoretical support.
