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

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

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.
