Influence of interference effects of spontaneous emission on the behavior and spectra of resonance fluorescence of a three-level atom in a strong wave field

An investigation is made of the influence of quantum interference processes accompanying radiative relaxation of excited states on the population dyna mics, total intensity, and spectra of the resonance fluorescence of three-l evel V-type atoms. Analytic expressions are obtained for the total intensit y and spectra of the resonance fluorescence taking into account the off-dia gonal nature of the radiative relaxation operator. It is shown that quantum interference process can substantially alter the total spontaneous emissio n intensity of the atoms and the population dynamics of the atomic levels, as well as the resonance fluorescence spectra.
