Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

Over the past few decades, coherent broadband spectroscopy has been widely used to
improve our understanding of ultrafast processes (eg, photoinduced electron transfer, proton …

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light
pulses. Currently two methods are capable of generating such pulses: post compression of …

The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul
Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in …

In the past decade, attosecond technology has opened up the investigation of ultrafast
electronic processes in atoms, simple molecules, and solids. Here, we report the application …

Optical soliton dynamics can cause extreme alteration of the temporal and spectral shape of
a propagating light pulse. This occurs at up to kilowatt peak powers in glass-core optical …

We present an experimental study of optical time-refraction caused by time-interfaces as
short as a single optical cycle. Specifically, we study the propagation of a probe pulse …

Unlike the capillaries conventionally used for gas-based spectral broadening of ultrashort (<
100 fs) multi-millijoule pulses, which produce only normal dispersion at usable pressure …

Ultrafast lasers reaching extremely high powers within short fractions of time enable a
plethora of applications. They grant advanced material processing capabilities, are effective …

The possibility to excite and control charges in matter on ultrafast timescales is a key
requisite to overcome the current limits of information transfer and data processing. The …
