Light polarization dynamics in self-confined beams and solitons propagating in photorefractive media

摘要

Soliton formation in photorefractive crystals with strong optical activity is analyzed. We shall demonstrate that self-confinement of the laser beam is not enough to define such a beam "a soliton": in fact this state is completely define by both intensity and polarization soliton dynamics. We report here the characterization of the soliton state for CW and pulsed beams.
