The description of the electronic structure of molecules in terms of molecular orbitals is a
highly successful concept in chemistry. However, it commonly fails if the electrons in a …

We demonstrate an angular high-harmonic spectroscopy method to probe the spinning
dynamics of a molecular rotation wave packet in real time. With the excitation of two time …

We report the observation of macroscopic field-free orientation, ie, more than 73% of CO
molecules pointing in the same direction. This is achieved through an all-optical scheme …

Strong-field ionization of molecules releases electrons which can be accelerated and driven
back to recombine with their parent ion, emitting high-order harmonics. This ionization also …

In this contribution to celebrate'25 years of recollision physics', we reflect on how the
quantitative rescattering (QRS) theory was developed during the 2007–9 period. A short …

Direct imaging of molecular dynamics is a long-standing goal in physics and chemistry. As
an emerging tool, high-order-harmonic spectroscopy (HHS) enables accessing molecular …

In recent years intense mid-infrared lasers with wavelength of a few microns have become
the standard tools for research in strong field physics laboratories worldwide. These lasers …

High-repetition-rate gas targets constitute an essential component in intense laser matter
interaction studies. The technology becomes challenging as the repetition rate approaches …

Photoionization of molecular species is, essentially, a multipath interferometer with both
experimentally controllable and intrinsic molecular characteristics. In this work, XUV …

A theory and method for a matrix-based reconstruction of molecular frame (MF)
photoelectron angular distributions (MFPADs) from laboratory frame (LF) measurements …
