An analysis is made of the propagation of a short coherent optical pulse in a three-level resonant medium with an essentially nonequidistant spectrum as a function of the degree of preexcitation of the medium. It is found that in addition to self-induced transparency and resonance scattering, stimulated Raman scattering (Stokes or anti-Stokes) should be observed under certain spatial phase-matching conditions. The area theorem is formulated for all radiation components. An analysis is made of the case of propagation of a resonant electromagnetic pulse of frequency ω in a system of three-level atoms having an equidistant spectrum. Under conditions of preexcitation of the medium at the frequency 2ω by longitudinal acoustic pulses, a scattered transverse acoustic wave at the frequency ω may be observed.

The resonance fluorescence of a two-level system irradiated by a smooth laser pulse is investigated. The author calculates higher-order correlation functions of the electromagnetic field explicitly in the limit of a very short pulse and demonstrate the presence of both antibunching and squeezing of the scattered light.

The kinetics of interaction of a coherent electromagnetic field with a periodic medium is considered for a two-wave case. Numerical solution of the generalized system of Maxwell-Bloch equations is obtained. It is noted that the self-induced selective suppression of Bragg reflection at a boundary and the suppression of the scattering of a field pulse in a medium could be observed experimentally while studying the interaction of a laser beam with resonant atoms or molecules in layered crystals.
