Nonlinear Interaction of Linearly Polarized Laser Radiation with Condensed Media and Overcoming the Diffraction Limit

摘要

We have analyzed known experimental results on the formation of periodic structures in condensed media under the action of a series of femtosecond linearly polarized laser pulses. The found examples of the formation of spatial periods of structures with a scale smaller than the diffraction optical limit in the condensed medium have been interpreted in terms of a nonlinear mathematical model, a one-dimensional unimodal logistic mapping that describes how a change in the period that is multiple of two depends on the changing control parameter.
