Figure 13.2: Experimental setup used for observing self-trapping of incoherent light, resulting
in the formation of a spatial incoherent soliton. (After Ref. [9]; (~) 1996 APS.)
13.3.3 Experimental Results
The first observation of the self-trapping of a spatially incoherent optical beam used
the slow-responding nonlinearity associated with photorefractive crystals [9]. Under
appropriate conditions, a CW beam propagated as a bright soliton of 30-~m width,
in spite of its partially coherent nature. Since the correlation length across the beam
intensity profile was much shorter than the beam
