Cavity-induced modifications to the resonance fluorescence and probe absorption of a laser-dressed V-type atom - art. no. 063807

A cavity-modified master equation is derived for a coherently driven, V-typ e three-level atom coupled to a single-mode cavity in the bad-cavity limit. We show that population inversion in both the bare- and dressed-state base s may be achieved, originating from the enhancement of the atom-cavity inte raction when the cavity is resonant with an atomic dressed-state transition . The atomic populations in the dressed-state representation are analyzed i n terms of the cavity-modified transition rates. The atomic fluorescence sp ectrum and probe absorption spectrum are also investigated, and it is found that the spectral profiles may be controlled by adjusting the cavity frequ ency. Peak suppression and Line narrowing occur under the appropriate condi tions.
