متن کاملEffects of coherent coupling of autoionizing states on multiphoton ionization.
coherent coupling of autoionizing states on multiphoton ionization" (1996). C. We present the experimental and theoretical investigation of the effects of the strong electromagnetic coupling of two autoionizing states (AIS's) on the photoionization properties of an atomic system. These effects are observed by probing the ladder system from the ground state of the atom through a weak two-photon ...
متن کاملElectron Correlation Effects in Nonresonant Multiphoton Ionization Processes
The role of electron correlations in nonresonant multiphoton processes of atoms is presented. The evidence for the validity of a lowest order perturbation theory (LOPT) approach for the laser field in the case of nonresonant processes is sketched. The growing consensus for a LOPT interpretation of even the multiply-charged ion spectra obtained with high intensity lasers is reviewed. Finally, a ...
متن کاملDouble multiphoton ionization of a model atom
A direct solution of the time-dependent Schrödinger equation ~TDSE! for a two-electron model atom in a strong electromagnetic field is used to extract probabilities for both single and double electron ionization. For three-photon ionization at a moderately strong intensity, the TDSE calculations find single ionization at 62%, single ionization with excitation at 10%, and double ionization at 3%...
متن کاملLippmann-Schwinger description of multiphoton ionization
Abstract We outline a formalism and develop a computational procedure to treat the process of multiphoton ionization (MPI) of atomic targets in strong laser fields. We treat the MPI process nonperturbatively as a decay phenomenon by solving a coupled set of the integral Lippmann-Schwinger equations. As basic building blocks of the theory we use a complete set of field-free atomic states, discre...
