ABSTRACT
We have studied the dynamical behavior of laser emission in optically pumped GaAs/AlGaAs lasers with picosecond time resolution. We find a saturation of the spontaneous emission above threshold and a homogeneous reduction of carrier lifetime down to about 70 ps. These data suggest a homogeneous gain saturation in GaAs/AlGaAs quantum well lasers, similar to conventional double heterostructure lasers.
