摘要	A two-section InGaSb/AlGaAsSb single quantum well (SQW) laser emitting at 2 mu m is presented. By varying the absorber bias voltage with a fixed gain current at 130 mA, passive mode locking at similar to 18.40 GHz, Q-switched mode locking, and passive Q-switching are observed in this laser. In the Q-switched mode locking regimes, the Q-switched RF signal and mode locked RF signal coexist, and the Q-switched lasing and mode-locked lasing happen at different wavelengths. This is the first observation of these three pulsed working regimes in a GaSb-based diode laser. An analysis of the regime switching mechanism is given based on the interplay between the gain saturation and the saturable absorption.
