摘要：
We present here the first experimental evidence of spontaneous laser filamentation with patterns other than hexagons, in a thin Kerr medium placed in front of a single backreflecting mirror. In particular, we observed hexagons-to-rolls transition and, by proper external seeding, generation of square-like patterns.
