摘要：
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 17.6 THz. 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 phase-locked multifrequency emissions, which leads to optical pulse trains at a repetition rate in excess of 10 THz.
