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 …

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 …

Tailoring the electric-field waveform of ultrashort light pulses forms the basis for controlling
nonlinear optical phenomena on their genuine, attosecond timescale. Here we extend …

The availability of high-energy pulses with durations shorter than the period of their carrier
frequency (sub-cycle) will reveal new regimes of strong-field light–matter interactions …

The realization of compact and efficient broadband mid-infrared (MIR) lasers has enormous
impacts in promoting MIR spectroscopy for various important applications. A number of well …

High-brightness sources of coherent and few-cycle-duration light waveforms with spectral
coverage from the ultraviolet to the terahertz would offer unprecedented versatility and …

We demonstrate how a scheme called advanced dual-chirped optical parametric
amplification (DC-OPA) that employs two kinds of nonlinear crystal (BiB3O6 and MgO-doped …

We theoretically investigate high harmonic generation (HHG) from silicon thin films with
thicknesses from a few atomic layers to a few hundreds of nanometers, to determine the …

Spectroscopy in the wavelength range from 2 to 11 μm (900 to 5000 cm− 1) implies a
multitude of applications in fundamental physics, chemistry, as well as environmental and …

Abstract Sub-10 attosecond pulses (APs) with half-cycle electric fields provide exceptional
options to detect and manipulate electrons in the atomic timescale. However, the availability …
