The rise time of intense radiation determines the maximum field strength atoms can be
exposed to before their polarizability dramatically drops due to the detachment of an outer …

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 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 …

We use a nonperturbative method to solve the time-dependent Schrödinger equation for an
electronic state of an atom subject to a very intense (> 10 13 W/cm 2) laser. The oscillating …

We present a method for calculating the spectrum emitted by an atom in an intense laser
field. This method is based on the direct use of the acceleration of the atomic electron rather …

The authors present theoretical studies of high-order harmonic generation in a rare-gas
medium. The experimental results obtained at Saclay with a 1064 nm Nd-YAG laser in the …

We present experimental and theoretical results on high-harmonic generation in noble
gases using an 805 nm, 25 fs, titanium-doped sapphire laser. The harmonic energies …

This book presents and describes a series of unusual and striking strong-field phenomena
concerning atoms and free electrons. Some of these phenomena are: multiphoton …

We describe in detail some properties of a one-dimensional model atom that has been used
for the study of multiphoton processes. We discuss static properties of the atom such as its …

Abstract Above-Threshold Ionization (ATI) is the name given to the absorption by an atomic
electron of more photons than are required for ionization. ATI was discovered in 1979 and is …
