Hexagonal Transverse Patterns in the Counter-Propagated Light Beams Interaction: Many-Body Approach

Abstract

The hexagonal patterns in nonlinear optics previously have been discovered experimentally [1,2] and numerically [3]. It was noted that the appearance of the hexagons is one of the displaying of strong counter-propagated light beams instability, in particular, in the media with Kerr-like nonlinearity.
