Abstract The word'attosecond'(1 as= 10− 18 s) officially entered the vocabulary of physics
when sub-femtosecond pulses of UV/XUV light produced either by nonlinear frequency …

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 …

Relativistic, nonlinear Thomson scattering by an electron of an intense laser field has been
investigated by computer simulation. Under a laser field with a pulse duration of 20-fs full …

Electromagnetic bursts of substantial energy on a nuclear time scale of 10− 21–10− 22 s
[zeptosecond (zs) to sub-zs] can theoretically be generated by a perawatt or multiterawatt …

The combination of several high order harmonics can produce an attosecond pulse train,
provided that the harmonics are locked in phase to each other. We present calculations that …

Electron transitions and emission of an atom interacting with a spatially inhomogeneous
ultrashort electromagnetic pulse are considered. The excitation and ionization probabilities …

A novel application of a free-standing transmission grating as a beam splitter in a Michelson-
type interferometer is described. The arrangement can operate in the XUV and soft X-ray …

The condition for the coherent addition of the relativistic nonlinear Thomson scattered
(RNTS) radiations from a group of electrons is derived. Numerical calculations show that …

We have solved the time-dependent Schrödinger equation describing the simultaneous
interaction of the He 1s2s 1 S state with two laser-generated pulses of trapezoidal or …

By use of a transmission-grating-based Michelson interferometer, second-order
interferometric as well as intensity autocorrelation traces of the third harmonic of a Ti …
