Interplay of the channel-closing and bound-bound transition resonances in multiphoton ionization and harmonic generation in intense laser pulses
A. D. Krupin, V. V. Strelkov, M. Yu. Ryabikin
In this paper, using a simplified model of the xenon atom, we numerically study the possibilities of efficient generation of coherent pulses in the XUV range through the resonant i…
Dark and bright autoionizing states in resonant high harmonic generation: simulation via 1D helium model
V. V. Strelkov
We study the role of dark and bright autoionizing states (AIS) in photoionization and high harmonic generation (HHG) using a 1D helium model. This model allows numerical integratio…
Spectral caustic in two-color high harmonic generation: role of Coulomb effects
V. A. Birulia, V. V. Strelkov
The high-order harmonic spectrum generated in two-color intense laser field under certain conditions has a pronounced maximum caused by the so called spectral caustic. Using a nume…
Attosecond pulse production using resonantly-enhanced high-order harmonics
V. V. Strelkov
We study theoretically the effect of the giant resonance in Xe on the phase difference between the consecutive high order resonantly-enhanced harmonics and calculate the duration o…
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…
