Abstract

An internal phase-shift mechanism can lead to the amplification of Raman solitons even in the presence of coherence decay and detuning. We study here the case of a Raman medium with strong ac Stark shift by using both analytical and numerical methods. Our results also suggest the possibility of propagating stable transient Raman solitons in optical fibers.
