Abstract

We study the spontaneous emission spectrum of a three-level Λ-type atom in a damped cavity using the resolvent operator. The shape of the spectrum is strongly influenced by the detuning and the coupling intensity between the atom and the cavity mode. Especially, we find that the splittings of the upper level of the three-level Λ-type atom are different in strong coupling regime, intermediate coupling regime and weak coupling regimes.
