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 …

Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has
enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as …

Resonant ultrafast excitation of infrared-active phonons is a powerful technique with which
to control the electronic properties of materials that leads to remarkable phenomena such as …

Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

We review the most recent progress in ultralow-noise mode-locked fiber lasers and fiber-
based frequency-comb sources. With the rapid progress in theory, measurement, and …

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 …

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 …

Optical parametric amplifiers (OPAs) exploit second-order nonlinearity to transfer energy
from a fixed frequency pump pulse to a variable frequency signal pulse, and represent an …

Abstract The word'attosecond'(1 as= 10− 18 s) officially entered the vocabulary of physics
when sub-femtosecond pulses of UV/XUV light produced either by nonlinear frequency …

The theoretical description and the experimental methods and results for above-threshold
ionization (ATI) by few-cycle pulses are reviewed. A pulse is referred to as a few-cycle pulse …
