Modification of the Raman response of a nonlinear-optical material can dramatically change the spectral and temporal evolution of ultrashort pulses, leading to new interesting and practically significant regimes of short-pulse dynamics. We show that, in fibers with a high Raman gain, solitonic spikes can arise only as transient features in the fast dynamics of ultrashort field waveforms. Enhanced Raman scattering induces a fast frequency downshift of these transients, preventing the formation of temporally and spectrally isolated solitons and giving rise to new highly efficient regimes of supercontinuum generation.
