| Zusammenfassung: | 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 1μm spectral range. The all-semiconductor laser generates transform-limited pulses as short as 590fs at a 3GHz repetition rate and an output power of 30mW. The pulse duration of the mode-locked laser was supported by the fast relaxation time of the saturable absorber of 1.0ps. |
