Investigation of transition dynamics in a quantum-dot laser optically pumped by femtosecond pulses

We investigated the behaviour of a quantum-dot edge-emitting laser, optically pumped by femtosecond pulses. We demonstrated that pulses generated by the laser from ground-state transitions have longer durations than those generated by the excited-states.
