Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has
enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Conical intersections allow electronically excited molecules to return to their electronic
ground state. Here, we observe the fastest electronic relaxation dynamics measured to date …

Proton transfer is one of the most fundamental events in aqueous-phase chemistry and an
emblematic case of coupled ultrafast electronic and structural dynamics,. Disentangling …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

Coherent soft x-ray (SXR) sources enable fundamental studies in the important water
window spectral region. Until now, such sources have been limited to repetition rates of 1 …

Ultrashort laser pulses are unique tools to trigger and probe the fastest charge dynamics in
matter, allowing the investigation of fundamental physical phenomena with unprecedented …

Air lasing from single ionized N 2+ molecules induced by laser filamentation in air has been
intensively investigated and the mechanisms responsible for lasing are currently highly …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

We show that attosecond core-level spectroscopy is a powerful tool for investigating
molecular dynamics due to its combined attosecond temporal resolution and the broad …
