Fluorescence Spectrum Of Three-level V-type Atoms

Since the 1970s,B.R.Mollow studied that the fluorescence spectra of the two-level atom driven by the strong field will have a three-peak structure,then resonant flu-orescence spectrum has been paid more and more attention.With the deepening of research,it was found that the fluorescence spectra in the cavity and the material will be split,narrowed and some now phenomena,so that Resonance fluorescence occupies a central position in quantum optics.In this paper,we first discuss the d-ifference between two-level atoms in the classical and quantum cavity fields.Then the fluorescence spectra of three-level V-type atoms in classical and dual-mode quan-turn cavities are discussed respectively.In order to physical mechanism clear,we use of dressed-atom approach to deal with atoms and drive field see the interaction and analyze the three-level atoms appear five peaks or seven peaks of the reasons.We investigate the effect of quantum interference between the two transition pathways from the excited doublet to the ground level of a driven V-type atoms on the spectral features of the resonance fluorescence emission.We find that quantum interference between two decay channels of the atom can greatly modify the fluorescence spec-trum.We show that ultrasharp lines and split lines can be produced in the resonance fluorescence spectra of a three-level atom through the mechanism of quantum inter-ference,and discusses the effect of different values on the fluorescence spectrum of?/?.
