The phase-space evolution for the instabilities in a CO2 laser with an intracavity saturable absorber is investigated experimentally. The different scenarios corresponding to limit cycles, homoclinic orbits and cycles involving two unstable points, and chaotic behavior are investigated. A theoretical analysis of the experimental results is sketched out.
