Creating attosecond breathing ions by coherent shake-up
James Tarrant, Přemysl Kolorenč, Margarita Khokhlova +2
Shake-up is a fundamental phenomenon in photoionisation of many-electron systems whereby the ionisation of one electron is accompanied by the simultaneous excitation of another. As…
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…
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…
A simple analytical alignment model for laser-kicked molecular rotors
A. Löhr, M. Ivanov, M. Khokhlova
We develop a mathematically simple yet accurate model for the single-pulse non-resonant impulsive alignment of thermal ensembles of linear molecules. We find that our molecular ali…
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…
Enantiosensitive steering of free-induction decay
Margarita Khokhlova, Emilio Pisanty, Serguei Patchkovskii +2
Chiral discrimination, a problem of vital importance, has recently become an emerging frontier in ultrafast physics, with remarkable progress achieved in multiphoton and strong-fie…
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…
Dialogue on analytical and ab initio methods in attoscience
Gregory S. J. Armstrong, Margarita A. Khokhlova, Marie Labeye +3
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 Review com…
High-order parametric generation of coherent XUV radiation
O. Hort, A. Dubrouil, M. A. Khokhlova +6
We observe a new regime of coherent XUV radiation generation in noble gases induced by femtosecond pulses at very high intensities. This XUV emission has both a reduced divergence…
Phase properties of the cut-off high-order harmonics
M. A. Khokhlova, V. V. Strelkov
The cut-off regime of high-order harmonic generation (HHG) by atoms in an intense laser field is studied numerically and analytically. We find that the cut-off regime is characteri…
High-order optical processes: towards nonperturbative nonlinear optics
V. V. Strelkov
We develop an approach describing nonlinear-optical processes in the strong-field domain characterized by the nonperturbative field-with-matter interaction. The polarization of an…
High-order harmonic generation and Fano resonances
V. V. Strelkov, M. A. Khokhlova, N. Yu. Shubin
We present a high harmonic generation theory which generalizes the strong-field approximation to the resonant case, when the harmonic frequency is close to that of the transition f…
Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation
S. Haessler, V. Strelkov, L. B. Elouga Bom +7
Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this…
