Scattering phenomena in strong radiation fields II

By continuing previous work, several different scattering and absorption phenomena in the presence of a strong, coherent, electromagnetic background field are considered from a unifying point of view to elucidate the essential similarities of these processes, in particular, in the limit of low frequencies of the radiation field. The connection with corresponding classical processes is investigated. The limitations of the low-frequency approach are considered, and consequences are discussed with respect to the possible physical implications and conditions of experimental verification.
