This paper has been prepared by the Symphony collaboration (University of Warsaw,
Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of …

We present a review of work that has been done during the last 10 years on atomic
scattering and reaction processes in bichromatic laser fields. Of particular interest will be the …

With the discovery of above-threshold ionization (ATI) by Agostini et al.(1979) intense-laser
atom physics entered the nonperturbative regime. These experiments recorded the …

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 …

Intense-field many-body S-matrix theory (IMST) provides a systematic ab initio approach to
investigate the dynamics of atoms and molecules interacting with intense laser radiation. We …

Using a simple model of strong-field ionization of atoms that generalizes the well-known 3-
step model from 1D to 3D, we show that the experimental photoelectron angular …

The first reported measurements of single attosecond pulses use laser dressed single-
photon extreme ultraviolet (XUV) ionization of gas atoms. The determination of XUV pulse …

A theory of above-threshold ionization of atoms by a strong laser field is formulated. Two
versions of the strong-field approximation (SFA) are considered, the direct SFA and the …

A review is presented of the rescattering plateau in laser-induced above-threshold ionization
and its various features as they were discovered over time. Several theoretical explanations …

Publisher Summary This chapter provides an overview on various scattering and reaction
processes taking place in a powerful laser field. These processes can be either laser …
