Soliton self-frequency shift for pulses with a duration less than the period of molecular oscillations.
The effect of stimulated Raman scattering on soliton propagation in fibers is studied for pulse durations comparable with or shorter than the molecular oscillation period. The self-frequency shift of a soliton in this interaction regime is calculated to be inversely proportional to the soliton duration and does not depend on both the characteristic frequency of the molecular oscillations and the Raman gain width of the medium.
