The steady-state rate equations for a junction laser containing a saturable optical loss are analyzed in terms of parameters typical of contemporaory stripe-geometry (AlGa)As lasers. The analysis reveals that under conditions which produce self-induced intensity pulsations the steady-state power output may also exhibit a bistability or hysteresis over a small range of current in the vicinity of threshold. Experimental observations made with (AlGa)As double-heterostructure lasers reveal that a nearly discontinuous behavior in the laser's output characteristic is, in fact, sometimes associated with the self-induced pulsations.
