The coherent resonant interaction of laser pulses shorter than the medium relaxation times (called ultrashort pulses) has been discussed previously in detail (1967–1970) for media consisting of two–level systems and gives rise to nonlinear coherent phenomena such as self induced transparency and soliton propagation in attenuating media [1–3]. In amplifying media these phenomena allow one to obtain very short and intense pulses. Molecular systems cannot be in general considered as the two-level systems, so there is a need to examine pulse propagation in many level-systems both theoretically and experimentally.
