Figure 7

Patterns obtained with propagation of a diverging elliptic-Gaussian beam through a defocusing nonlinear medium. The medium was placed at several positions after the beam waist. Δ = 18, α = 300, G 0 = 30, and q = [ z 0 + .12 i , z 0 + .21 i ] cm. Aperture was 12 times of the input beam size along both the axes. The successive frames (from left to right) are for z 0 = −3.0, -4.0 and -5.0 cm.

Patterns obtained with propagation of a converging elliptic-Gaussian beam through a defocusing nonlinear medium. The medium was placed at several positions before the beam waist. Δ = 18, α = 300, G 0 = 30, and q = [ z 0 + .12 i , z 0 + .21 i ] cm. Aperture was 12 times of the input beam size along both the axes.
