| Abstract: | Competition among modes in an annular CO2 laser has been experimentally and numerically analyzed. During the coexistence of different patterns, each of them resulting
from the interaction of two transverse modes with opposite angular momentum, chaos has been experimentally detected. A numerical
model, derived from the Maxwell-Bloch equations and including symmetry breaking terms, enables the interpretation of the main
experimental features.
