Title: Self-pulsations of lasers with saturable absorber: dynamics and bifurcations
Abstract: We consider the Yamada model, a set of three differential equations constituting a simple model for self-pulsations in (semiconductor) lasers with saturable absorber. A complete picture of all possible dynamics is presented in terms of two-dimensional bifurcation diagrams, in which we find a Bogdanov–Takens bifurcation as an organizing center. This shows that pulses are indeed created in a homoclinic bifurcation (or saddle connection). For suitable values of (relative) absorption we also find regions of multistability, yielding the possibility of hysteresis. The influence of noise on the dynamics is discussed.
