ABSTRACT
We revisit the laser model with cavity loss modulation, from which
evidence of chaos and generalized multistability was discovered in
1982. Multistability refers to the coexistence of two or more
attractors in nonlinear dynamical systems. Despite its relative
simplicity, the adopted model shows us how the multistability
depends on the dissipation of the system. The model is then tested
under the action of a secondary sinusoidal perturbation, which can
remove bistability when a suitable relative phase is chosen. The
surviving attractor is the one with less dissipation. This control
strategy is particularly useful when one of the competing attractors
is a chaotic attractor.
