Active and passive mode locking of strip buried heterostructure lasers is observed using an external cavity consisting of a lens and a mirror. Using the second-harmonic-generation method to obtain the second-order autocorrelation function we obtain Gaussian pulses as short as 35.7 psec (FWHM) at a 1.9-GHz repetition rate. The optical spectrum of the mode locked laser consists of longitudinal modes of the composite cavity spaced by approx.0.05 A, whose amplitudes are modulated by the 2.09-A-mode spacing of the laser itself, and contained under a Gaussian envelope of 9.5-A FWHM. Additional very sharp structure (approx.1.6-psec FWHM) in the autocorrelation is shown to result from the presence of several laser mode groups.
