N2 - We report a theoretical investigation of a control scheme of a single-L system in pump-probe feedback spectroscopy. The feedback controls the phase of one of the fields, and its action is triggered by a nontrivial unraveling of the quantum operation of detection of spontaneous photons emitted by an atom. Within the framework of Markovian master equations, it is shown that the shape and width of the 'dark' resonance of coherent population trapping can be controlled within very wide limits. In addition, sharp resonant-like structures in the field's work dependence on the Rabi frequencies are revealed and explained.
