In this tutorial we discuss the macroscopic aspects of the extreme nonlinear frequency
conversion process of high-order harmonic generation. For most, this entails describing the …

We report attosecond-scale probing of the laser-induced dynamics in molecules. We apply
the method of high-harmonic spectroscopy, where laser-driven recolliding electrons on …

The latest achievements in high-order harmonic generation of ultrashort pulses in plasma
plumes are reviewed. These studies demonstrate the attractiveness of this advanced …

Harmonic generation of laser radiation from ionized particles in the extreme ultraviolet range
at the conditions of the phase matching between the femtosecond driving field and …

The exterior complex scaling (ECS) method is applied in the framework of time-dependent
density-functional theory (TDDFT) to study multiphoton ionization (MPI) and high-order …

Novel methods of coherent short-wavelength sources generation require thorough analysis
for their further amendments and practical implementations. In this work, we report on the …

The first demonstration of quasi-phase-matching during high-order harmonic generation
(HHG) of laser radiation in multi-jet plasmas produced on the silver and chromium targets …

We propose to shape attosecond pulses in the extreme ultraviolet (xuv) by creating and
tuning a spectral minimum in the high-order harmonic generation (HHG) spectrum by using …

High-order harmonic generation in laser-induced plasmas is analyzed from the point of view
of presence of either molecular or atomic components. Comparison of boron carbide …

We study high-order-harmonic generation (HHG) by the incident laser beam in the Laguerre-
Gaussian mode with a nonzero topological charge. We find that the harmonic signal in the …
