Twisted Gaussian Schell-model solitons - art. no. 036618

We show that a certain class of spatially partially coherent solitons, name ly, twisted Gaussian Schell-model solitons, exists in a logarithmically sat urable nonlinear medium with a noninstantaneous temporal response. Unlike p reviously reported Gaussian Schell-model solitons, those discussed here car ry a position-dependent twist phase, which vanishes in the fully coherent l imit. We demonstrate that the presence of the twist phase provides an oppor tunity for controlling the degree of spatial coherence of such solitons wit hout affecting their intensity.
