An investigation is made of the effects of cross-phase modulation and pump depletion on pulse dynamics in the stimulated Raman scattering process. It is shown that cross-phase modulation may significantly affect the frequency chirp of the pulse even to the point of reversing the sign of the chirp. As a consequence, solitonlike pulse compression using Raman amplification may become impossible with the Stokes pulse in the anomalous-dispersion regime. The chirp reversion effect is weakened by pulse walk-off, which, if strong enough, retains the frequency characteristics of the inherent self-phase modulation.
