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 advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

The ability to perform attosecond-pump attosecond-probe spectroscopy (APAPS) is a
longstanding goal in ultrafast science. While first pioneering experiments demonstrated the …

The generation of power-and wavelength-scalable few optical cycle pulses remains one of
the major challenges in modern laser physics. Over the past decade, the development of …

Multi-electron dynamics in atoms and molecules very often occur on sub-to few-femtosecond
time scales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have …

Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis,
and light harvesting. To capture such dynamics in real-time, femtosecond to attosecond light …

We investigate the spatial characteristics of high-order harmonic radiation generated in
argon and observe cross-like patterns in the far field. An analytical model describing …

Time-resolved resonant magnetic scattering in the soft-x-ray range is a powerful tool for
accessing the spatially resolved and element-specific spin dynamics in magnetic materials …

Currently, laser systems based on active elements doped with Yb3+ with simultaneously
high pulse repetition rates and high peak power are in demand for many applications. High …

In this paper, a 3-dimensional photoelectron/ion momentum spectrometer (reaction
microscope) combined with a table-top attosecond beamline based on a high-repetition rate …
