Abstract: | Based on color-locking noisy field correlation in three Markovian
stochastic models, phase dispersions of the Raman- and
Rayleigh-enhanced four-wave mixing (FWM) have been investigated. The
phase dispersions are modified by both linewidth and time delay for
negative time delay, but only by linewidth for positive time delay.
Moreover, the results under narrowband condition are close to the
nonmodified nonlinear dispersion and absorption of the material.
Homodyne and heterodyne detections of the Raman, the Rayleigh and
the mixing femtosecond difference-frequency polarization beats have
also been investigated, separately. |
