The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a
single field oscillation cycle has opened a new era in the experimental investigation of …

The field of laser-matter interaction traditionally deals with the response of atoms, molecules,
and plasmas to an external light wave. However, the recent sustained technological …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

We study the generation of high-harmonic radiation by Bloch electrons in a model
transparent solid driven by a strong midinfrared laser field. We solve the single-electron time …

The accurate measurement of time lies at the heart of experimental science, and is relevant
to everyday life. Extending chronoscopy to ever shorter timescales has been the key to …

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 …

Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Precision time references in space are of major importance to satellite-based fundamental
science, global satellite navigation, earth observation, and satellite formation flying. Here we …

The history and current status of the Keldysh theory of strong field ionization are reviewed.
The focus is on the fundamentals of the theory, its most important applications and those …

In attosecond and strong-field physics, the acquisition of data in an acceptable time
demands the combination of high peak power with high average power. We report a 21 W …
