We consider a basic rate-equation model for the gains and intensities of two identical lasers that are mutually coupled via fast saturable absorbers. A numerical bifurcation study with the software package AUTO reveals the prevalence of multistability between different types of stable solutions of the system, including stationary states and in-phase, anti-phase and intermediate-phase oscillations.
