Reproducible bistable and hysteretical behavior is obtained from an external cavity laser, with one absorbing and one gain semiconductor diode, when the absorber diode is operated below its transparency threshold current density. The laser diodes are optically coupled without parasitic conductance or photoconductive electrical coupling and the bistable laser operates in a single longitudinal mode. Under certain conditions the laser oscillates at around 20 Hz with millisecond optical switching times.
