Ionization-free femtosecond UV pulse filamentation resulting from non-perturbative Kerr effect saturation due to transient photoexcitation of molecules
V. V. Strelkov, A. V. Shutov, V. D. Zvorykin
Our experimental and numerical study of filamentation of the 248 nm 100 fs pulses in air, nitrogen, and oxygen at atmospheric pressure shows that the densities of photoelectrons in…
Propagation effects in resonant high-harmonic generation and high-order frequency mixing in laser plasma
Vasily V. Strelkov, Margarita A. Khokhlova
We study the phase matching of resonant high-harmonic generation (HHG) and high-order frequency mixing (HFM) in plasma. We solve numerically the propagation equations coupled with…
Resonant high-order harmonic generation by indium ions
Alexander I. Magunov, Vasily V. Strelkov
High-order harmonic generation in multiphoton ionization regime is studied theoretically to examine the resonant effects of the generating particle. We solve the time-dependent Sch…
Phase-matching gating for isolated attosecond pulse generation
Vasily V. Strelkov, Margarita A. Khokhlova
We investigate the production of an isolated attosecond pulse~(IAP) via the phase-matching gating of high-harmonic generation by intense laser pulses. Our study is based on the int…
Macroscopic effects in generation of attosecond XUV pulses via high-order frequency mixing in gases and plasma
V. A. Birulia, M. A. Khokhlova, V. V. Strelkov
We study the generation of attosecond XUV pulses via high-order frequency mixing (HFM) of two intense generating fields, and compare this process with the more common high-order ha…
Role of blue-shift length in macroscopic properties of high-harmonic generation
Margarita Khokhlova, Vasily Strelkov
The production of brighter coherent XUV radiation by intense laser pulses through the process of high-harmonic generation (HHG) is a central challenge in contemporary nonlinear opt…
Chromatic aberrations correction of attosecond high-order harmonic beams by flat-top spatial shaping of the fundamental beam
K. Veyrinas, M. Plach, J. Peschel +16
Attosecond pulses created by high-order harmonic generation in gases often exhibit strong chromatic aberrations, arising from the broad bandwidth and wavelength-dependent nonlinear…
Generation of Attosecond Pulses with Controllable Carrier-Envelope Phase via High-order Frequency Mixing
V. A. Birulia, M. A. Khokhlova, V. V. Strelkov
Advancing table-top attosecond sources in brightness and pulse duration is of immense interest and importance for an expanding sphere of applications. Recent theoretical studies [N…
Polarisation control of quasi-monochromatic XUV produced via resonant high harmonic generation
M. A. Khokhlova, M. Yu. Emelin, M. Yu. Ryabikin +1
We present a numerical study of the resonant high harmonic generation by tin ions in an elliptically-polarised laser field along with a simple analytical model revealing the mechan…
Mirrorless focusing of XUV high-order harmonics
L. Quintard, V. Strelkov, J. Vabek +8
By experimentally studying high-order harmonic beams generated in gases, we show how the spatial characteristics of these ultrashort XUV beams can be finely controlled under standa…
