FIG. 1.

Typical fundamental ML pulsations (, ). Left: time traces of the emitted field intensities (a) and the carrier functions averaged over the gain and SA sections (c), respectively. Right: axial distributions of the optical fields (b) and the carrier functions (d) at the time moment .

FIG. 2.

ML pulsation with a large plateau at the trailing edge of the pulse. The same as in Fig. 1, but for .

FIG. 3.

Modal analysis of a ML regime shown in Fig. 2. (a) Calculated time trace of the field intensity emitted at the gain section facet (thick gray curve) and its reconstruction using 50, 20, and 4 modes with largest (thin curves). (b) Bullets give a parametric representation of the modal phases (above) and amplitudes (below) vs modal frequencies . Optical spectrum of the emitted field is shown by the solid line. Bullets of different sizes indicate modes used for the field reconstruction in panel (a).

FIG. 4.

Experimental AC measurements (a) and reconstructed pulse shapes using FROG technique (b) at fixed voltage of the SA section and several values of the injection currents into the gain section.
