Evolution of initial distortions of wave beams in a nonlinear medium

K. S. Gochelashvili, A. N. Starodumov, I. M. Uzunov


Abstract: An analysis is made of the development of an instability in focused beams as a result of transient thermal self-interaction. The instability increments are determined. Estimates are obtained of the regions of stable propagation of a pulse.
