Abstract:
The authors investigate the spectral tuning of the exciton resonance of a surface quantum well saturable absorber mirror for the generation of subpicosecond pulses, employing an optically pumped semiconductor disk laser in the 1 µm spectral range. The all-semiconductor laser generates transform-limited pulses as short as 590 fs at a 3 GHz repetition rate and an output power of 30 mW. The pulse duration of the mode-locked laser was supported by the fast relaxation time of the saturable absorber of 1.0 ps.
