Cherenkov Radiation and Relaxed Optics

Abstract

Short review of basic peculiarities of Cherenkov radiation is represented. Influences of various types of irradiation on formation the Cherenkov radiation are discussed. Conditions of receiving Cherenkov radiation as phenomenon of Nonlinear Optics (multiphoton absorption in regime of saturation of excitation) are formulated. Three types of models are used for the representation of proper experimental data. Experimental data of receiving the cascade of volume laser-induced destruction in silicon carbide are analyzed. The role of shork processes, including Cherenkov radiation, and diffraction stratification of focused light in the formation experimental picture is observed. The modified Rayleygh model is used for the estimation the sizes and form of receiving nanovoids. Good agreements of modeling and experimental data were received
