Optical patterns beyond the Kerr-limit: Flowers, stars and others

Abstract

Recently, interest in pattern forming systems with single-mirror-feedback [1] shifted from Kerr media to systems with saturable or even more complicated nonlinearities [2, 3, 4, 5]. Here we report on a rich, at the first sight even confusing, variety of patterns and relate them to general features of pattern formation. In our experiment a circularly polarized, spatially filtered beam of a cw dye laser traverses a sodium cell and is fed back by a plane mirror (Fig. 1).
