Abstract

15-THz trains of a few-tens-of-femtoseconds optical pulses were generated by modulation instability oscillation in a colliding-pulse mode-locked dye laser. A repeatable and stable modulation instability regime was obtained with the laser operating in the anomalous-dispersion regime and with a low saturable-absorber concentration. Autocorrelation measurements indicate that subpulses were completely separated in real time. Variations of the modulation with the pump power and the amount of dispersion in the cavity are in good agreement with modulation instability theory.

Fig. 1
Fig. 1

Autocorrelation traces of the modulation instability oscillation in a CPM dye laser for different jet thicknesses. The thickness of the absorber jet was increased from ~40 to 50 μm. The period of modulation instability subpulses changes from 140 fsec (a) to 80 fsec (c). One division corresponds to 320 fsec in time.

Fig. 2
Fig. 2

Autocorrelation traces of the modulation instability oscillation in the CPM dye laser for different amounts of intracavity glass. The period of modulation instability subpulses changes from 160 to 64 fsec because of the increase of intracavity glass. This corresponds to subpulse repetition rates up to 15.6 THz. One division corresponds to 320 fsec in time.
