We explore recently predicted multifrequency 2{pi} solitons in multicascade stimulated Raman scattering (SRS) that was mode locked by the dynamics of population at a Raman quantum transition; we show that these solitons are eigensolitons of a general solitary-wave solution. Soliton components at each frequency are bright pulses of the same (Lorentzian) shape, in contrast to the familiar bright{endash}dark soliton pair in regular SRS and to 1/cosh regular 2{pi} solitons. Coherent interference of these components gives rise to a train of well-resolved subfemtosecond pulses. From an observation viewpoint the simplest SRS 2{pi} solitons are so-called bright{endash}bright solitons in noncascade SRS with either two (laser + Stokes) or three (e.g., laser + Stokes + anti-Stokes) components. {copyright} {ital 1996 Optical Society of America.}
