Relaxed Optics: Modeling and Discussions

Problem of modeling Nonlinear and Relaxed Optical processes and its interactions are analyzed. Surface processes of Relaxed Optics and methods of its modeling are discussed. Short experimental data and appropriate methods of modeling: cascade theory of excitation of proper chemical bonds in the regime of saturation the excitations: surface plasmon-polariton model and its modifications, are used for the explanation of represented experimental data. Volume processes of Relaxed Optics and methods of its modeling (on B. Sharma method and added by A.Manenkov models). Problems of generation and modeling laser-induced filaments (modified Rayleygh model of diffractive rings, elements of Lugovoy-Prokhorov theory of moving focuses, interference of Cherenkov radiation and modified Rayleygh model of creation laser-induced nanovoids) in various media (gases, liquids and solid) are represented and discussed. We show that these may be explanation from unitary point of view. Questions of similarity, dimensions and Relaxed Optics are analyzed too.
