When an atom or molecule is exposed to a short intense laser pulse, electrons that were
removed at an earlier time may be driven back by the oscillating electric field of the laser to …

The quantum-mechanical transition amplitudes for atomic and molecular processes in
strong laser fields are expressed in the form of multidimensional integrals of highly …

High-harmonic generation driven by two-color counter-rotating circularly polarized laser
fields was recently demonstrated experimentally as a breakthrough source of bright …

A theory of above-threshold ionization of atoms by a strong laser field is formulated. Two
versions of the strong-field approximation (SFA) are considered, the direct SFA and the …

A review is presented of the rescattering plateau in laser-induced above-threshold ionization
and its various features as they were discovered over time. Several theoretical explanations …

A comprehensive quantitative rescattering (QRS) theory for describing the production of high-
energy photoelectrons generated by intense laser pulses is presented. According to the …

Stimulated by the recent demonstration of the first bright source of circularly polarized high
harmonics, we examine the attosecond pulse trains generated by a group of such …

The velocity map of the above-threshold ionization electron spectrum at long laser
wavelength exhibits a characteristic structure normal to the laser polarization, which has the …

The strong-field approximation for ionization of diatomic molecules by an intense laser field
is generalized to include rescattering of the ionized electron off the various centers of its …

The low-energy structure (LES) in the energy spectrum of above-threshold ionization of rare-
gas atoms is reinvestigated from three different points of view. First, the role of forward …
