Effects of Zeeman degeneracy on the steady-state properties of an atom interacting with a near-resonant laser field: Resonance flourescence

Effects of the atomic Zeeman degeneracy on the resonance fluorescence spectrum of a closed two-level atom with arbitrary ground-state angular momentum ${\mathit{J}}_{\mathit{g}}$ and excited-state, angular momentum ${\mathit{J}}_{\mathit{e}}$ are studied in detail. Especially interesting are the narrow structures due to the spontaneous Raman scattering and the incoherent Rayleigh scattering. Results for the cycling transition of a Cs atom are presented as part of the examples.
