Abstract: | Secondary bifurcations of hexagonal patterns are analyzed in a model of a single-mirror arrangement with an alkali metal vapor as the nonlinear medium. A stability analysis of the hexagonal structures is performed numerically. Depending on the wavenumber of the hexagons different instabilities are predicted. Some of them take place at a finite wavenumber and result in the formation of structures with twelve spatial modes. These structures are compared with those observed experimentally. |
