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…
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…
