Abstract

Transverse modulational instabilities of counterpropagating beams are well known to lead to the spontaneous formation of a variety of complex spatial structures, among them conical rings, pairs of spots (rolls), or arrays of spots arranged in hexagonal or square symmetry. Among the systems that have revealed to show similar phenomena, photorefractive single feedback configurations [1] allow to realize a rich variety of spontaneously formed patterns, including squeezed hexagons or square patterns [2].
