Abstract

The generalized Schrödinger equation with the Kerr and saturation nonlinearities is used to investigate the filamentation instability and localization of arbitrarily large amplitude optical pulses in nonlinear media. The existence of finite amplitude optical clumps (optical solitons or light bullets) is demonstrated. Conditions under which the filamentation instability and light localization arise are presented.
