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 …

Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

Extremely narrow optical resonances in cold atoms or single trapped ions can be measured
with high resolution. A laser locked to such a narrow optical resonance could serve as a …

Laser science has been successful in producing increasingly high-powered, faster and
smaller coherent light sources,,,,,,,,. Examples of recent advances are microscopic lasers …

The generation of ultrashort pulses is a key to exploring the dynamic behaviour of matter on
ever-shorter timescales. Recent developments have pushed the duration of laser pulses …

In principle, the temporal beating of superposed high harmonics obtained by focusing a
femtosecond laser pulse in a gas jet can produce a train of very short intensity spikes …

Harmonic generation is a general feature of driven nonlinear systems. In particular high-
order harmonic generation (HHG) in atomic gases is the basis for producing attosecond …

Ultrafast lasers, which generate optical pulses in the picosecond and femtosecond range,
have progressed over the past decade from complicated and specialized laboratory systems …

Recoil-ion and electron momentum spectroscopy is a rapidly develo** technique that
allows one to measure the vector momenta of several ions and electrons resulting from …

Time-dependent density-functional theory (TDDFT) describes the quantum dynamics of
interacting electronic many-body systems formally exactly and in a practical and efficient …
