PULSED BEAM SELF-FOCUSING

摘要

Nonlinear optical radiation propagation bounded in time (pulse) and in space (beam) is considered. We investigate temporal-spatial self-action, when pulse decompression influences on the beam self-focusing. An exact analytical solution of coupled nonlinear differential equations for pulse and beam widths is derived. Influence of dispersion spreading of the pulse on the formation of spatial soliton is considered.
