Nonperturbative regime of low-order harmonic generation in intense low-frequency laser field
S. A. Bondarenko, V. V. Strelkov
We find the atomic response to the intense femtosecond laser pulse via solving numerically the three-dimensional non-stationary Schrödinger equation (TDSE) for a model atom and ca…

Role of plasma waves in rescattering processes in intense laser fields
V. V. Strelkov, S. A. Bondarenko, I. V. Smetanin
Rescattering of the photoelectron at its parent ion underlie a number of phenomena in intense laser field interaction with matter, such as high harmonic generation, attosecond puls…

Fano resonance in XUV generated by helium with few-cycle intense laser pulses and its classical analogy
S. A. Bondarenko, V. V. Strelkov
We integrate numerically the Schrödinger equation for the model helium atom irradiated by intense few-cycle laser pulse and find the emitted XUV spectra. They demonstrate resonant…
