Stabilization of a one-dimensional short-range model atom in intense laser fields
نویسندگان
چکیده
The stabilization of atoms in the presence of very intense and short laser pulses has been proposed and confirmed in various numerical simulations (e.g. Su et al). A question was then raised by several authors (Chen and Bernstein, Krainov and Preobrazhenskii, and Geltman) concerning the possibility of producing such stabilization in a one-dimensional model atom with zero range of electron–nucleus interaction. In this paper we report evidence of stabilization through the suppression of ionization for such a model atom. We find that the use of a highfrequency laser pulse is necessary for such a realization.

Ionization suppression of excited atomic states beyond the stabilization regime
A two-dimensional model atom is employed to study the ionization behavior of initially excited atomic states in highly-frequent intense laser pulses beyond the dipole approximation. An additional regime of ionization suppression is found at laser intensities where the stabilization effect is expected to break down. The appearance of this effect is due to a strong coupling of the initial wave fu...

متن کاملOn the absence of bound-state stabilization through short ultra-intense fields
We address the question of whether atomic bound states begin to stabilize in the short ultra-intense field limit. We provide a general theory of ionization probability and investigate its gauge invariance. For a wide range of potentials we find an upper and lower bound by non-perturbative methods, which clearly exclude the possibility that the ultra intense field might have a stabilizing effect...

A relativistic theory for two-stream free electron laser (FEL) with a one-dimensional helical wiggler and ion-channel guiding in the presence of self-fields are presented. A dispersion relation (DR) which includes coupling between the electromagnetic and the electrostatic waves is derived from a fluid model, with all of the relativistic terms related to the transverse wiggler motion. This DR is...
