Abstract
We show the possibility of achieving experimentally a Takens-Bogdanov bifurcation for the nonlinear interaction of two transverse modes (l=/-1) in a CO2 laser. The system has a basic 0(2) symmetry which is per turbed by some symmetry-breaking effects that still preserve the Z2 sy mmetry. The pattern dynamics near this codimension-two bifurcation und er such symmetries is described. This dynamics changes drastically whe n the laser properties are modified.
