This chapter shows that the radiative behavior of a two-level atom in free space is drastically modified when the atom is confined to a cavity with dimensions comparable to the emitted wavelength. In the latter situation the photon cannot escape to infinity, but is instead reflected from the cavity walls to re-excite the atom. In the resonant wave approximation, the evolution of the atom-photon system in a cavity is described by the Jaynes-Cummings model. For an atom initially in the excited state, the excited-state occupation probability first collapses to an apparent steady-state value of 1/2, but later experiences a revival with oscillations around 1/2. This system has been experimentally realized by a device called a micromaser.
Keywords: Jaynes-Cummings model, collapse, revival, micromaser
