Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

High‐power laser sources are widely used in industrial precision processing and act as a
new platform for strong‐field physics research using peak power over petawatt. This review …

The motion of electrons in the microcosm occurs on a time scale set by the atomic unit of
time—24 attoseconds. Attosecond pulses at photon energies corresponding to the …

High-harmonic generation (HHG) traditionally combines~ 100 near-infrared laser photons to
generate bright, phase-matched, extreme ultraviolet beams when the emission from many …

Ultrafast laser sources operating in the mid-infrared (mid-IR) region, which contains the
characteristic fingerprint spectra of many important molecules and transparent windows of …

Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

Femtosecond pulse generation was pioneered four decades ago using mode-locked dye
lasers, which dominated the field for the following 20 years. Dye lasers were then replaced …

Establishing the structure of molecules and solids has always had an essential role in
physics, chemistry and biology. The methods of choice are X-ray and electron diffraction …

This paper has been prepared by the Symphony collaboration (University of Warsaw,
Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of …

The availability of high-energy pulses with durations shorter than the period of their carrier
frequency (sub-cycle) will reveal new regimes of strong-field light–matter interactions …
