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 …

A brief review is given regarding ultrafast laser micromachining of materials. Some general
experimental observations are first provided to show the characteristics of ultrafast laser …

The dependence of the strength of the electron-phonon coupling and the electron heat
capacity on the electron temperature is investigated for eight representative metals, Al, Cu …

The ultrafast laser excitation of matters leads to nonequilibrium states with complex solid-
liquid phase-transition dynamics. We used electron diffraction at mega–electron volt …

Melting is a common and well-studied phenomenon that still reveals new facets when
triggered by laser excitation and probed with ultrafast electron diffraction. Recent …

The structure of our material world is characterized by a large hierarchy of length scales that
determines material properties and functions. Increasing spatial resolution in optical imaging …

Structural transformations in a shallow surface region of a bulk Ag (001) target irradiated by
a femtosecond laser pulse are investigated in large-scale atomistic simulations and …

In this contribution, we highlight the state of the art in the determination of structures with
ultrafast electrons and X‐rays. We provide our perspectives and reflections on the principles …

We present the main specifications of the newly constructed Swiss Free Electron Laser,
SwissFEL, and explore its potential impact on ultrafast science. In light of recent …

The mechanisms and kinetics of short pulse laser melting of single crystal and
nanocrystalline Au films are investigated on the basis of the results of simulations performed …
