A review of studies of high-order harmonic generation in plasma plumes is presented. The
generation of high-order harmonics (up to the 101st order, λ= 7.9 nm) of Ti: sapphire laser …

The perceived dichotomy between analytical and ab initio approaches to theory in
attosecond science is often seen as a source of tension and misconceptions. This Topical …

The methods of enhancement of the strong high-order harmonics of femtosecond pulses in
laser-induced plasma are demonstrated. It comprises the application of the four techniques …

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 …

We report the demonstration of strong resonance enhancement of a single high-order
harmonic in the extreme ultraviolet (XUV) region generated from the interaction of a …

Studying the dynamics of dark states is challenging due to their inability to undergo single-
photon emission or absorption. This challenge is made even more difficult for dark …

An experimental study of high-order harmonic generation in In, InSb, InP, and InGaP
plasmas using femtosecond laser radiation with variable chirp is presented. Intensity …

The results of enhanced high-order harmonic generation (HHG) in laser-produced plasmas
using a two-color laser pump (98% of 800 nm and 2% of 400 nm) are presented. Even (up to …

We demonstrate the generation of high-order harmonics of laser pulses in palladium and
cadmium plasmas. We adjusted the wavelength of driving pulses to investigate the …

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 …
