Stability analysis of a laser with two modulated saturable absorbers

The stability analysis of a model for a laser system with two modulated saturable absorbers, each one modulated at a different frequency, is performed. The model is based on four equations describing the temporal evolution of the photon flux, the population inversion in the active media, and the saturation coefficients of each saturable absorber. The system dynamics is discussed in order to find stable system control regions.
