Abstract :
In this report, we present experimental study of spectrally-resolved dynamics of InGaAs/GaAs/AlGaAs QW laser diodes emitting through multiple electron and hole quantum levels. 4 mm-long lasers with 7 mum stripes were pumped with short 150 ns electrical pulses with low 16 kHz repetition rate in order to avoid overheating. This has allowed to apply pumping current amplitudes up to 10 A, to the level of hundreds of thresholds.
