Abstract:
The spontaneous emission of an excited two-level emitter driven by a strong
classical coherent low-frequency electromagnetic field is investigated. We find
that for relatively strong laser driving, multi-photon processes are induced,
thereby opening additional decay channels for the atom. We analyze the
interplay between the strong low-frequency driving and the interfering
multiphoton decay channels, and discuss its implications for the spontaneous
emission dynamics.
