FIG. 8.2 (a) The distribution of the local optical power in the 2D fundamental soliton created by a laser beam in the extraordinary polarization, launched into the photorefractive crystal, as shown in Fig. 8.1 . The shape and stability of the soliton are supported by the photoinduced lattice created in the ordinary polarization. (b) The same soliton as produced by a numerical solution of the respective theoretical model ( Fleischer et al., 2003 ). More about this image found in (a) The distribution of the local optical power in the 2D fundamental solit...

FIG. 4.5 Experimentally observed robust soliton-like rotating (2+1)D patterns in the form of “propellers” composed of two (a) or three (b) “blades” (individual ones are identified by means of white dots). They were created in the photorefractive crystal, which features the saturable self-focusing nonlinearity. The white arrows indicate the direction of the rotation in the transverse plane ( Zhang et al., 2010 ).
