Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

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 …

We present a semiclassical two-step model for strong-field ionization that accounts for path
interferences of tunnel-ionized electrons in the ionic potential beyond perturbation theory …

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 …

Recent developments in laser sources operating in the mid-IR (3–8 μ m) have been
motivated by the numerous possibilities for both fundamental and applied research. One …

Under ideal conditions, quantum metrology promises a precision gain over classical
techniques scaling quadratically with the number of probe particles. At the same time, no-go …

We explore ionization and rescattering in strong mid-infrared laser fields in the nondipole
regime over the full range of polarization ellipticity. In three-dimensional photoelectron …

In this Letter, a high-stability, linearly polarized mode-locked polarization-maintaining (PM) E
r 3+-doped fluoride fiber oscillator at∼ 2.8 µ m is presented for the first time, to the best of …

We propose a method to implement absorbing layers for the numerical solution of the time-
dependent Schrödinger equation (TDSE) in the open domain. The method is based on …
