Experimental advances with laser intensities above 1 TW/cm 2, with pulse durations
between roughly 50 and 5 fs, have led to the discovery of new atomic effects that include …

High-order harmonic generation (HHG) in gases leads to short-pulse extreme ultraviolet
(XUV) radiation that is useful in a number of applications, such as attosecond science and …

We review the phenonomena which occur in multiphoton physics when the electric field of
the applied laser radiation becomes comparable with the Coulomb field strength seen by an …

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 …

Ionization is the dominant response of atoms and molecules to intense laser fields and is at
the basis of several important techniques, such as the generation of attosecond pulses that …

Field emission of electrons underlies great advances in science and technology, ranging
from signal processing at ever higher frequencies to imaging of the atomic-scale structure of …

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 …

A recently formulated theory of high-order harmonic generation by low-frequency laser fields
[Anne L'Huillier et al., Phys. Rev. A 48, R3433 (1993)] allows us to study the phase of the …

Multiphoton Processes in Atoms in intense laser-light fields is gaining ground as a
spectroscopic diagnostic tool. The authors present descriptions of processes occurring in …

Strong–laser–field physics is a research direction that relies on the use of high-power lasers
