Role of initial coherence in the generation of harmonics and sidebands from a strongly driven two-level atom.

摘要: We investigate the coherent and incoherent contributions of scattering spectrum strongly driven two-level atoms as a function initial preparation atomic system. The ``phasing'' superposition excited ground states is shown to influence generation both harmonics hyper-Raman lines. In particular, we point out conditions under which harmonic can be inhibited at expense Our numerical findings are supported by approximate analytical evaluation in dressed state picture.
