In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

Multiphoton excitation and ionization of two-electron atoms under strong laser pulses, with
emphasis on double excitation, is reviewed. After an introduction to the basic concepts of …

This book represents the first comprehensive treatment of the subject, covering the
theoretical principles, present experimental status and important applications of short-pulse …

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 …

Ultrafast laser pulses from a Ti: sapphire laser centered at 800 nm, with 26 fs pulse duration,
were used to generate coherent soft-x-ray harmonics, at wavelengths down to 2.7 nm (460 …

High-harmonic generation is a universal response of matter to strong femtosecond laser
fields, coherently upconverting light to much shorter wavelengths. Optimizing the conversion …

The development of lasers capable of producing high-intensity pulses has opened a new
area in the study of light-matter interactions. The corresponding laser fields are strong …

For three-dimensional many-electron time periodic Hamiltonians which are invariant under
dynamical symmetry of order N we prove that only the (nN±1) th, n= 1, 2,…, harmonics are …

The generation of high harmonics created during the interaction of a 2.5 ps, 1053 nm laser
pulse with a solid target has been recorded for intensities up to 10 19 W cm− 2. Harmonic …

In recent years high-order harmonic generation (HG) has become one of the major topics of
super-intense laser-atom physics. Generally speaking, high harmonics are generated when …
