The high-order harmonic generation (HHG) in xenon is studied by using the time-dependent density-functional theory. The dynamics of all electrons on the outer 4th and 5th atomic shells is considered with subsequent separation of contributions of diff

We present a way for generating coherent tunable electromagnetic radiation through dc to ac field conversion by an ionization front. The conversion is caused by the excitation of leaky waves behind the transversely limited ionization front propagatin

We study the generation of low-order harmonics during the interaction of helium atoms with intense elliptically-polarized laser pulses in the presence of a static electric field. Based on the solution of the three-dimensional time-dependent Schrödin

The optimal waveform of an ionizing pulse and the corresponding maximum values of the density of residual terahertz currents are found analytically. The solutions obtained can be realized using multicolor femtosecond pulses containing a field at the

A mechanism of a significant increase in the yield of Brunel harmonics, which are the lowest odd harmonics generated in a plasma in the process of tunnel ionization of atoms and molecules by an intense laser pulse, has been proposed and analyzed. Thi

The high harmonic generation (HHG) in xenon is studied by using the time-dependent density-functional theory for active 4th and 5th atomic shells. The HHG spectra are calculated for different intensities and carrier-envelope phases of a laser pulse.

We investigate the high harmonic generation during the interaction of the femtosecond laser field with oriented asymmetric diatomic molecules in the presence of an external static electric field. Based on the numerical solution of the time-dependent
