We analyze the doubly differential electron momentum distribution in above-threshold ionization of atomic hydrogen by a linearly-polarized mid-infrared laser pulse. We reproduce side rings in the momentum distribution with forward-backward symmetry previously observed by Lemell \textit{et al.} in Phys. Rev. A \textbf{87}, 013421(2013), whose origin, as far as we know, has not been explained so far. By developing a Fourier theory of moir\'{e} patterns, we demonstrate that such structures stems…

Super-interference in atomic photoionization: Moiré patterns in momentum maps

We theoretically investigate on the origin of lateral ring structures in the doubly differential momen-tum distribution for atomic ionization by laser pulses in the midinfrared spectral region. We

Holographic interference in atomic photoionization from a semiclassical standpoint

A theoretical study of the interference pattern imprinted on the doubly differential momentum distribution of the photoelectron due to atomic ionization induced by a short laser pulse is developed

Holographic interferences in photoelectron spectra: different approaches

Abstract We perform a theoretical study of the holographic structures in photoelectron spectra for ionization of hydrogen atoms induced by short laser pulses. To elucidate the nature of the



Electron angular distributions in near-threshold atomic ionization

We present angle- and energy-resolved measurements of photoelectrons produced in strong-field ionization of Xe using a tunable femtosecond laser. An occurrence of highly oscillatory patterns in the

Intra- and intercycle interference of angle-resolved electron emission in laser-assisted XUV atomic ionization

A theoretical study of ionization of the hydrogen atom due to an XUV pulse in the presence of an infrared (IR) laser is presented. Well-established theories are usually used to describe the

Interference oscillations in the angular distribution of laser-ionized electrons near ionization threshold.

A complex two-dimensional interference pattern that resembles above threshold ionization (ATI) rings at higher energies and displays Ramsauer-Townsend-type diffraction oscillations in the angular distribution near threshold is found.

Diffraction at a time grating in above-threshold ionization: The influence of the Coulomb potential

We analyze the photoelectron emission spectrum in atomic above-threshold ionization by a linearly polarized short-laser pulse. Direct electrons can be characterized by both intracycle and intercycle

Electron emission perpendicular to polarization direction in laser assisted XUV atomic ionization

We present a theoretical study of ionization of the hydrogen atom due to an XUV pulse in the presence of an IR laser with both fields linearly polarized in the same direction. In particular, we study

Laser-assisted inelastic rescattering during above-threshold ionization.

Model calculations for helium at 780 nm and intensities near W/${\mathrm{cm}}^{2}$ show that the effect of the field on the total probability of promoting an electron from the ionic ground state is small, but the laser alters the final excited-state populations, rapidly ionizing any excited bound states.

Interference structure of above-threshold ionization versus above-threshold detachment

Laser-induced electron detachment or ionization of atoms and negative ions is considered. In the context of the saddle-point evaluation of the strong-field approximation (SFA), the velocity maps of

Signatures of photon effect in the tunnel regime

It is widely believed that intense-field ionization occurs either though a ‘multiphoton’ mechanism (for Keldysh parameter γ > 1) or through a tunnelling mechanism (or ‘field ionization’), for γ < 1.

Rings in above-threshold ionization: A quasiclassical analysis.

It is demonstrated that contributions from the direct tunneling processes in the absence of rescattering are not sufficient to describe the observed ATI spectra, and the high-energy portion of the spectrum, including recently discovered rings, are due to rescattering processes.
