Abstract

The propagation of intense subpicosecond pulses in single-mode fibers is under the influence of group-velocity dispersion, self-phase modulation, and stimulated Raman scattering (SRS): it may be described in terms of a nonlinear Schrödinger equation with a delayed contribution to the third-order nonlinear polarization.^1-3 Applications may involve pulse compression by an external grating in the normal dispersion regime of the fiber or through the fiber itself in the anomalous dispersion regime by means of Raman soliton generation and self-frequency shift.
