Rabi oscillations in extreme ultraviolet ionization of atomic argon
Open accessAbstract
We demonstrate Rabi oscillations in nonlinear ionization of argon by an intense femtosecond extreme ultraviolet (XUV) laser field produced by high-harmonic generation. We monitor the formation of $\mathrm{A}{\mathrm{r}}^{2+}$ as a function of the time delay between the XUV pulse and an additional near-infrared (NIR) femtosecond laser pulse, and show that the population of an $\mathrm{A}{\mathrm{r}}^{+*}$ intermediate resonance exhibits strong modulations both due to an NIR laser-induced Stark shift and XUV-induced Rabi cycling between the ground state of $\mathrm{A}{\mathrm{r}}^{+}$ and the $\mathrm{A}{\mathrm{r}}^{+*}$ excited state. Our experiment represents a direct experimental observation of a Rabi-cycling process in the XUV regime.

A description of the calculation of the transition dipole moment from the ionic argon ground state (Ar + ) to an effective ionic excited state (Ar + * ), based on the relation between the transition dipole moment and the oscillator strength of the transition; some calculated oscillator strengths are compared with literature values showing a good agreement between them (Sec. 1). Also, a description of the physical quantities used in the quantum mechanical model applied in the Letter to fit the experimental data, i.e., the Ar 2+ ionization yield as a function of the XUV-NIR time delay for different NIR intensities (Sec. 2).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
