AB  - The aim of this study is the elaboration of a mathematic model for describing the action of saturable absorber lasers. The anticipant approach for that purpose takes into consideration the phenomenological manner of essential physical parameters necessary to saturable absorber lasers and their influences on the optical bistability. We are going to examine theoretically the optical bistability in the three mode saturable absorber lasers. We`ll focus on the case where the two active and absorber milieus sustain a dominant inhomogeneous broadening for a Fabry-Perot cavity. From an interferometric point of view the bistable behavior due to a nonlinear material inside a Fabry-Perot cavity is studied. Starting from the system of the Rate Equation (RAE), we have solved numerically this type of equation for stationary case. We have elaborated program in Matlab allowing us to determine the effect of this optical bistability and to draw the curves representing the density of the photons in the pumping function of the active milieu in the case if the spontaneous emission is neglected.
