Attosecond science offers formidable tools for the investigation of electronic processes at the
heart of important physical processes in atomic, molecular and solid-state physics. In the last …

The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

Giant half-cycle attosecond pulse generation in the coherent bremsstrahlung emission
regime is proposed for laser pulses with normal incidence on a double-foil target, where the …

Combining results from several techniques of attosecond spectroscopy, we show that
ionization gating of high-harmonic emission on the leading edge of the driving pulse …

In the past two decades high-harmonic generation (HHG) has become a key process in
ultrafast science due to the extremely short time structure of the underlying electron …

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 …

As a compact and burgeoning alternative to synchrotron radiation and free-electron lasers,
high harmonic generation (HHG) has proven its superiority in static and time-resolved …

Isolated attosecond pulses with a duration of 88 as are generated in the spectral range of 29–
72 eV using double optical gating technique. The gate width is set to be shorter than half the …

We describe a complete technological system at Imperial College London for Attosecond
Science studies. The system comprises a few-cycle, carrier envelope phase stabilized laser …
