SELF-CONSISTENT SOLUTIONS OF THE PROBLEM OF THE INTERACTION OF A 2-FREQUENCY FIELD WITH A SYSTEM OF 3-LEVEL ATOMS IN THE FORM OF A PHASE-MODULATED SIMULTON AND A RAMAN SOLITON

This paper discusses features of the interaction of a system of three- level atoms with a bichromatic electromagnetic field. Steady-state sol utions are found in the form of unimodal and nonunimodal solitary wave s corresponding to a pair of pulses in the form of a simulton or a Ram an soliton. An analytic form of the solutions is found, corresponding to a phase-modulated simulton and a Raman soliton. The conditions are determined for exciting them. The resulting solutions are of interest from the standpoint of the mechanism for forming the two-frequency cou pled excitations observed in various experiments.
