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 …

Since the first isolated attosecond pulse was demonstrated through high-order harmonics
generation (HHG) in 2001, researchers' interest in the ultrashort time region has expanded …

Powerful and stable attosecond pulse sources have the potential for wide application in
ultrafast science. For this purpose, we have produced a soft X-ray supercontinuum with a …

We report the observation of multiple ionization of argon through multi-XUV-photon
absorption induced by an unprecedentedly powerful laser driven high-order harmonic …

Abstract Short wavelength Free-Electron Lasers (FELs) are among the newest light sources
available to scientists to probe a wide range of phenomena, with chemical, physical and …

Ghost imaging, Fourier transform spectroscopy, and the newly developed Hadamard
transform crystallography are all examples of multiplexing measurement strategies …

We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. In Roadmap I, we focus on the …

We report the experimental observation of ghost imaging with paired x-ray photons, which
are generated by parametric downconversion. We use the one-to-one relation between the …

The output power of a free electron laser (FEL) has extremely high variance even when all
FEL parameter set points are held constant because of the stochastic nature of the self …

We demonstrate a mid-infrared optical parametric chirped pulse amplifier (OPCPA),
delivering 2.1 µm center wavelength pulses with 20 fs duration and 4.9 mJ energy at 10 kHz …
