In this thesis, the resonance fluorescence spectra of a A-type three-level atom is calculated, which is driven by two bichromatic fields having the same difference of the frequency. In addition, the influence of the relative phase difference on the fluorescence spectra are considered. It is found that the fluorescence spectra of the atom are deeply depend on the relative difference and the appearance and cancellation of the fluorescence are obtained by changing the relative phase difference.
