Abstract: The formation and competition of patterns in an annular CO2 laser has been experimentally and numerically analyzed. The temporal evolution of the different spatial structures increases its richness and complexity during the coexistence of different patterns. A model based on the Maxwell-Bloch equations, including a symmetry breaking term, provides a numerical interpretation of the main experimental features.
