Nonlinear Optics


The results of numerical solution of the nonlinear Schrödinger equation modeling nonstationary self-focusing and filamentation of high-power ultra-short laser radiation in atmospheric air and water are presented. The comparison of the major characteristics of the light and plasma filaments formed in these media is carried out.
