The milestones of attosecond optics research in the last 15 years are briefly reviewed, and
the latest trends in applications in gaseous and condensed matter are introduced. An …

Attosecond science is a growing new field of research and potential applications which
relies on the development of attosecond light sources. Achievements in the generation and …

Circular dichroism (CD) describes the different responses of a chiral object to circularly
polarized light of opposite handedness and serves as the basis of most chirality-sensitive …

Multiphoton ionization of potassium atoms with a sequence of two counter-rotating circularly
polarized femtosecond laser pulses produces vortex-shaped photoelectron momentum …

We demonstrate the generation of extreme-ultraviolet (XUV) free-electron laser (FEL) pulses
with time-dependent polarization. To achieve polarization modulation on a femtosecond …

RMT is a programme which solves the time-dependent Schrödinger equation for general,
multielectron atoms, ions and molecules interacting with laser light. As such it can be used to …

Multistart spiral vortex patterns are predicted for the electron momentum distributions in the
polarization plane following ionization of the helium atom by two time-delayed circularly …

Photoionization of matter is one of the fastest electronic processes in nature. Experimental
measurements of photoionization dynamics have become possible through attosecond …

We investigate the role of excited states in high-order harmonic generation by studying the
spectral, spatial, and temporal characteristics of the radiation produced near the ionization …

The resonant dynamic Stark effect, observed in the Autler-Townes (AT) splitting, plays a
central role in ultrafast strong-field physics. Recent experiments have demonstrated the …
