Abstract
A circularly polarized enlarged beam with a cw dye laser traverses a sodium cell and is fed back by a plane mirror. Magnetization is created in the sodium ground state and brings about a nonlinearity in the system. In a suitably chosen, oblique external magnetic field the homogeneous solution shows a nonlinear resonance-like behavior. A linear stability analysis reveals that in wide parameter regimes both the low and high transmission branches are unstable against transverse perturbations. A weakly nonlinear analysis to second order predicts the appearance of negative hexagons on the high transmission branch and positive hexagons on the low transmission branch. Flower-like and star-shaped patterns were also observed in this region.
