Abstract
The formation and stabilization of spatio-temporal patterns in an annular C O2 laser is studied. We give experimental and numerical evidence of the rol e of a small spatial perturbation (consisting of a thin metallic wire inser ted in the optical cavity) in the selection and stabilization of patterns.
