Some Problems of Modeling the Shock Processes of Relaxed Optics

Abstract

Basic peculiarities of modeling the shock processes of Relaxed Optics are discussed. It was shown that these processes may be having nonequilibrium and irreversible nature. Bond between radiated and non-radiated relaxation or processes of Nonlinear and Relaxed Optics is observed. Physical-chemical and electrodynamics’ aspects of these phenomena are analyzed. Modified Rayleygh models and basic theories of Cherenkov radiation are used for the observation of represented experimental data of 4H-SiC. We show that femtosecond laser irradiation may be generated Cherenkov radiation, which is source of further generation of cascade damages in irradiated matter. Comparative analysis the methods of modeling shock waves processes and cascade model of excitation in regime of saturation the excitation are used for modeling the laser-induced breakdown of irradiated matter.
