This letter reports the first results of a study of the excitation of ultrashort pulses in cascade stimulated Raman scattering in a single-mode optical fiber. The use of multisoliton contraction in a fiber with a shifted dispersion has made it possible to produce light pulses containing just barely more than three optical oscillation periods.
