The smallness of the velocity $$v$$ of laser-field-induced motion of electrons compared to the speed of light c is one of the fundamental physical factors limiting the efficiency of nonlinear optical processes in plasma media. It has been shown in th

Experiments on the generation of high optical harmonics demonstrating that relativistic regimes of interaction of radiation with matter can be implemented in the field of mid-infrared laser pulses with a peak power of 0.3 TW have been reported. The o

We identify the physical factors that limit the terahertz (THz) yield of an optical rectification (OR) of ultrashort multiterawatt laser pulses in large-area quadratically nonlinear crystals. We show that the THz yield tends to slow its growth as a f

Ultrafast laser-plasma interactions driven by ultrashort terawatt laser pulses are shown to give rise to a bright multioctave microwave radiation, whose polarization and spatial mode structure provides a sensitive probe for laser-driven plasma electr

2-TW, 30-fs, 800-nm laser radiation and its second harmonic are used to form a filament in low pressure gas cell. This filament forms a bright source of terahertz pulses. For 1-20 mbar gas pressure we registered a hundred-fold increase of THz yield c

We demonstrate a multicompartment, power-scalable beam-line design in which sub-40-fs, terawatt field waveforms are tailored in space and time for downstream pulse compression to few-cycle pulse widths attained right at the site where the intense las

We present experimental studies of long-distance transmission of ultrashort mid-infrared laser pulses through atmospheric air, probing air dispersion in the 3.6–4.2-μm wavelength range. Atmospheric air is still highly transparent to electromagneti

High-order harmonic generation (HHG) is one of the central effects in strong-field nonlinear-optical physics [1]. Within the past two decades, HHG has been at the heart of a paradigm-shifting breakthrough to attosecond physics [2]. Much less limeligh
