Abstract
Above-threshold ionization (ATI) is a phenomenon observed in multiphoton ionization experiments in intense laser fields. This process is characterized by a large number of evenly spaced peaks in the photoelectron energy spectrum. These peaks correspond to the absorption of n o+s photons by an atom which requires only n o photons to ionize. This is a special feature of ATI distinct from other multiphoton ionization processes, i.e., there are a significant number of radiative transitions between continuum states of the atom.KeywordsMultiphoton IonizationIntense Laser FieldZeroth Order SolutionCoupling Matrix ElementCoulomb Wave FunctionThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
