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 argon by a strong 2 ω pulse were probed as a function of the relative phase of a weaker ω probe pulse. Numerical simulations solving the time-dependent Schr¨odinger equation (TDSE) displayed a sensitive dependence of the doubly differential momentum distribution on the relative phase between the ω and 2… 



Phase delays in ω−2ω above-threshold ionization

Relative phases of atomic above-threshold ionization wavepackets have been investigated in a recent experiment [L. J. Zipp, A. Natan, and P. H. Bucksbaum, Optica 1, 361-364 (2014)] exploiting

Probing electron delays in above-threshold ionization

Recent experiments have revealed attosecond delays in the emission of electrons from atoms ionized by extreme UV light, offering a glimpse into the ultrafast nature of light-induced electron

Multiphoton interaction phase shifts in attosecond science

This paper shows that interferometric experiments in attosecond and free-electro lasers are subjected to large phase effects due to the accumulation of interaction phases with each exchanged laser

Intracycle and intercycle interferences in above-threshold ionization: The time grating

Within a semiclassical description of above-threshold ionization (ATI) we identify the interplay between intracycle and intercycle interferences. The former is imprinted as a modulation envelope on

Laser-assisted photoionization: Streaking, sideband, and pulse-train cases

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

Spiral-like holographic structures: Unwinding interference carpets of Coulomb-distorted orbits in strong-field ionization

We unambiguously identify, in experiment and theory, an overlooked holographic interference pattern in strong-field ionization, dubbed ``the spiral,'' stemming from two trajectories where the

Application of the saddle-point method to strong-laser-field ionization

The quantum-mechanical transition amplitude of an ionization process induced by a strong laser field is typically expressed in the form of an integral over the ionization time of a highly oscillatory

Time Delays from One-Photon Transitions in the Continuum

We experimentally resolve the time delay of electron wave packets arising from one-photon transitions in the continuum. This allows us to determine and quantify the angular momentum dependence of the

It is all about phases: ultrafast holographic photoelectron imaging

A historic account in which a connection with laser-induced electron diffraction (LIED) is established is established, a summary of the main holographic structures encountered and their underlying physical mechanisms, and a broad discussion of the theoretical methods employed.
