Abstract

We proposed and demonstrated a novel method for the evaluation of optical pulse trains generated by a multifrequency continuous-wave Raman laser operating at a mode separation of 17:6THz. This approach is based on the detection of a nonlinear signal arising from the intensity modulation of a pulse train, which should provide a useful means for measuring the deviation from phase locking of multifrequency lasers. Our results suggest that an optimization of intracavity dispersion allows the generation of phaselocked multifrequency emissions, which leads to optical pulse trains at a repetition rate in excess of 10 THz.
