We present a theoretical study of atomic laser-assisted photoionization emission (LAPE). We consider an atom driven by a linearly polarized XUV laser in two different scenarios: i) a single attosecond pulse (in both the streaking and sideband regimes) and ii) an attosecond pulse train. The process takes place assisted by a linearly polarized infrared (IR) laser field. In all these cases the energy and angle-resolved photoelectron spectrum (PES) is determined by a leading contribution, related…

Semiclassical strong-field theory of phase delays in $\omega -2\omega$ above-threshold ionization

Phase and time delays of atomic above-threshold ionization were recently experimentally explored in an ω − 2 ω setting [Zipp et al , Optica 1 , 361 (2014)]. The phases of wavepackets ejected from

XUV+IR photoionization of argon atoms: selection of sideband orders

We present a theoretical study of atomic ionization due to an XUV pulse in the presence of an infrared laser. Within the strong field approximation and considering the periodicity and symmetry of the

Two-color XUV+NIR femtosecond photoionization of neon in the near-threshold region

Results of angle-resolved electron spectroscopy of near-threshold photoionization of Ne atoms by combined femtosecond extreme ultraviolet and near infrared fields are presented. The dressed-electron

Atomic photoionization in combined intense XUV free-electron and infrared laser fields

We present a systematic study of the photoionization of noble gas atoms exposed simultaneously to ultrashort (20 fs) monochromatic (1–2% spectral width) extreme ultraviolet (XUV) radiation from the

The soft-photon approximation in infrared-laser-assisted atomic ionization by extreme-ultraviolet attosecond-pulse trains

We use the soft-photon approximation, formulated for finite pulses, to investigate the effects of the dressing pulse duration and intensity on simulated attosecond pump–probe experiments employing

Two-colour IR+XUV spectroscopies: the “soft-photon approximation”

We address several questions related to the nonlinear ionization processes observed when atoms are in the simultaneous presence of intense and coherent infrared (IR) and extreme ultraviolet (XUV)

Attosecond physics: facing the wave–particle duality

Recent progress in generation and control of intense optical fields has given rise to isolated soft x-ray pulses with durations significantly below 1 fs. These constitute a tool of unprecedented

Symphony on strong field approximation

The main novel part of the presented theory concerns generalizations of SFA to time-dependent treatment of two-electron atoms, allowing for studies of an interplay between Electron Impact Ionization and Resonant Excitation with Subsequent Ionization.
