Notice of RetractionPropagation of partially coherent solitons in photorefractive crystal

Abstract

We investigate the propagation dynamics of one dimensional partially coherent solitons in logarithmically saturable photorefractive media by using the coherent density theory, specially using this approach to study the self-trapping behavior of coherent beam. It is shown that the solitons can propagate stationary. Moreover, the other dynamics evolution of beam is discussed, that when the value of degree of coherence is departure from the set of the value of self-trapping, the beam continually expands and contracts. The evolution properties of coherent components that consist of partially coherent beams are also analyzed in detail.
