Abstract
We investigate the formation and evolution of spatial solitons with light beams propagating in quadratic nonlinear media under conditions for second-harmonic generation in quasi-phase-matched samples. We study the properties of the solitons as a function of the periodicity of the domain-reversal process involved in the quasi-phase-matching techniques, and we show the effects introduced by random shifts of the nominal domain length.Keywords
