A mode-locking mechanism by active gain modulation is studied numerically and experimentally. The parameter window for the emission of stable pulse trains was found. Pulses as short as 3ps (~0.5pJ) were characterized by second-order autocorrelation.
Keywords: Infrared and far-infrared lasers; mode-locked lasers; semiconductor lasers; quantum cascade lasers
