Abstract

A stationary distribution of populations in a three-level quantum system interacting with three intense monochromatic fields resonant to two allowed and one forbidden transition is determined for three possible configurations of the considered system. The obtained algebraic expressions for populations of levels are exact within the frameworks of RWA and dependent on the phases of fields even in the limit of strong field intensities. The latter circumstance causes the absorption line profile to be noisy due to random phase modulation of fields. The sets of parameters of the system and field are founded at which the populations of all the levels are equal to 1/3 also with the regions where a resonance-like dependence of level populations on the difference of field phases takes place.
