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 …

Establishing the structure of molecules and solids has always had an essential role in
physics, chemistry and biology. The methods of choice are X-ray and electron diffraction …

We review the progress made over the past 15 years in understanding and exploiting the
physical scaling of strong-field atomic processes. These advances were enabled by theory …

Strong-field physics is currently experiencing a shift towards the use of mid-IR driving
wavelengths. This is because they permit conducting experiments unambiguously in the …

Visualizing chemical reactions as they occur requires atomic spatial and femtosecond
temporal resolution. Here, we report imaging of the molecular structure of acetylene (C2H2) …

The quantitative rescattering theory (QRS) for high-order harmonic generation (HHG) by
intense laser pulses is presented. According to the QRS, HHG spectra can be expressed as …

The time-dependent surface flux (t-SURFF) method is introduced for computing strong-field
infrared (IR) photo-ionization spectra of atoms by numerically solving the time-dependent …

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 …

Strong-field photoelectron holography and laser-induced electron diffraction (LIED) are two
powerful emerging methods for probing the ultrafast dynamics of molecules. However, both …

We report on nonsequential double ionization of Ar by a laser pulse consisting of two
counterrotating circularly polarized fields (390 and 780 nm). The double-ionization …
