Abstract: The onset of deterministic chaos in lasers is studied by referring to the invariant properties of low dimensional attractors, in order to isolate the characteristics of chaos from the random fluctuations due to the coupling with a thermal reservoir. For this purpose, attention is focused on single model homogeneous line lasers, whose dynamics is ruled by a low number of coupled variables. In the examined cases, experiments and theoretical model are in close agreement. In particular, when many attractors co-exist for the same parameter values (generalized multistability) the presence of random noise induces long lived transients with 1/f like low frequency spectra. These are due to jumps over different basins of attraction (so called “hyperchaos”).
