We suggest a high-order harmonic generation (HHG) model describing enhancement of the
generation efficiency for the harmonic resonant with the transition between the ground and …

Research on high-order harmonic generation in laser-produced plasmas is reviewed. We
analyze the conditions for the generation of harmonics (up to the 101st order, λ= 7.9 nm) in …

The development of both theoretical and experimental work on the photoionization of atomic
ions over the last 20 years forms the subject of this review. The availability of spectroscopic …

We have successfully demonstrated intensity enhancement of a single high-order harmonic
at a wavelength of 46.76 nm by using low-ionized tin ions in a laser-ablation plume as the …

In high-order harmonic generation in low-dense media, the application of two-colored pump
has been shown to enhance odd-order harmonics, as well as the generation of strong even …

In order to explain the recently observed strong intensity enhancement of a single high-order
harmonic we analyze high-order harmonic generation (HHG) from low-ionized laser plasma …

This book represents the first comprehensive treatment of high-order harmonic generation in
laser-produced plumes, covering the principles, past and present experimental status and …

The resonance-enhanced harmonics in laser-induced arsenic and selenium plasmas are
studied at the quasi-phase-matching (QPM) conditions. We demonstrate that the …

Strong intensity enhancement or extinction of some single harmonics is observed in high-
harmonic generation from 48 fs Ti: sapphire laser pulses propagating through preformed low …

The plasmas produced on the surfaces of the transition metals from the fifth period of the
periodic table (Rh, Ru, Zr, and Nb) were used for the high-order harmonic generation of 65 …
