Spontaneous decay processes in a classical strong low-frequency laser field
arXiv:2007.03406 · doi:10.1103/PhysRevA.102.013718
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.
