Short, intense laser pulses can be used to access the transition regime between classical
and quantum optical responses in dielectrics. In this regime, the relative roles of inter-and …

We study photoionization of argon atoms excited by attosecond pulses using an
interferometric measurement technique. We measure the difference in time delays between …

This book's coverage builds from basic underlying theory to more complex ideas related to
attosecond optics. It shows how the generation of attosecond optical pulses requires …

This tutorial presents an introduction to the interaction of light and matter on the attosecond
timescale. Our aim is to detail the theoretical description of ultra-short time delays and to …

In ultrafast spectroscopy, the temporal resolution of time-resolved experiments depends on
the duration of the pump and probe pulses, and on the control and characterization of their …

How quanta of energy and charge are transported on both atomic spatial and ultrafast
timescales is at the heart of modern technology. Recent progress in ultrafast spectroscopy …

The long-standing scientific quest of real-time tracing electronic motion and dynamics in all
states of matter has been remarkably benefited by the development of intense laser-based …

We present experimental measurements and theoretical calculations of photoionization time
delays from the 3 s and 3 p shells in Ar in the photon energy range of 32–42 eV. The …

We study resonant two-color two-photon ionization of helium via the 1 s 3 p P 1 1 state. The
first color is the 15th harmonic of a tunable Ti: sapphire laser, while the second color is the …

Attosecond delay lines are key to enable time-resolved measurements on atoms, molecules,
plasma and solid-state materials. This tutorial review presents the current status of a wide …
