Attoscience is the emerging field that accesses the fastest electronic processes occurring at
the atomic and molecular length scales with attosecond (1 as= 1 0− 18 s) time resolution …

This review presents the current state of research on the generation and application of
subfemtosecond (or attosecond, where 1 as $= 10^{-18}\{\text {s}} $) ultraviolet and X-ray …

The long-standing scientific quest of real-time tracing electronic motion and dynamics in all
states of matter has been remarkably benefited by the development of intense laser-based …

The conditions required for the production of isolated attosecond pulses from relativistically
oscillating mirrors (ROM) are investigated numerically and experimentally. In simulations …

Real-time observation of ultrafast dynamics in the microcosm is a fundamental approach for
understanding the internal evolution of physical, chemical and biological systems. Tools for …

Recent developments in extreme ultraviolet (XUV) and x-ray radiation sources have pushed
pulse energies and durations to unprecedented levels that opened up the era of non-linear …

The interaction of ultra-intense laser pulses with matter opened the way to generate the
shortest light pulses available nowadays in the attosecond regime. Ionized solid surfaces …

ELI-ALPS, one of the three pillars of the Extreme Light Infrastructure (ELI) project, will be in a
unique position to offer dedicated experimental platforms for ultrashort time-resolved …

Spatial properties of high-order harmonic beams produced by high-intensity laser-matter
interactions carry rich information on the physics of the generation process, and their …

We review the main research directions ongoing in the development of extreme ultraviolet
sources based on high-harmonic generation for the synthesization and application of trains …
