High-order harmonic generation (HHG) in gases leads to short-pulse extreme ultraviolet
(XUV) radiation that is useful in a number of applications, such as attosecond science and …

Ultrafast processes in matter, such as the electron emission after light absorption, can now
be studied using ultrashort light pulses of attosecond duration (10− 18 seconds) in the …

This tutorial presents an introduction to power scaling concepts for high-order harmonic
generation (HHG) and attosecond pulse production. We present an overview of state-of-the …

Electron dynamics induced by resonant absorption of light is of fundamental importance in
nature and has been the subject of countless studies in many scientific areas. Above the …

Attosecond delay lines are key to enable time-resolved measurements on atoms, molecules,
plasma and solid-state materials. This tutorial review presents the current status of a wide …

We determine relative photoemission time delays between valence electrons in different
noble gas atoms (Ar, Ne and He) in an energy range between 31 and 37 eV. The atoms are …

Autoionization, which results from the interference between direct photoionization and
photoexcitation to a discrete state decaying to the continuum by configuration interaction, is …

One of the most ubiquitous techniques within attosecond science is the so-called
reconstruction of attosecond beating by interference of two-photon transitions (RABBIT) …

We describe a versatile and compact beamline for attosecond spectroscopy. The setup
consists of a high-order harmonic source followed by a delay line that spatially separates …

We apply a spectrally-resolved electron interferometry technique to the measurement of the
spectral phase in the vicinity of the 3s 1 3p 6 4p Fano resonance of argon. We show that it …
