Paper Abstract

Within the framework of the Akhmanov-Vorontsov model the transverse spatial-temporal dynamics of the phase shift u(x,y,t) of a laser beam (LB) is investigated numerically for the system with Kerr nonlinearity to which 2D feedback is applied. Principles of the analysis of the LB transverse dynamics are discussed that allow us to explain and predict the form of the phase shift u(x,y,t) depending on the parameters of the large-scale transformation of the field of LB in the feedback loop, the nonlinearity parameter, the diffusion coefficient and the relaxation time of molecules of the nonlinear medium (liquid crystal). The regimes of the periodic variation of the phase shift u(x,y,t) are described. The ways of the quantitative estimation of structurization processes are suggested.
