Summary
Observing Rabi oscillations with extreme ultraviolet (XUV) pulses is challenging. This study proposes a method using XUV-induced photoionization in Helium to detect these oscillations via superfluorescence, enabling ultrafast nonlinear dynamics control.
Area of Science:
- Atomic Physics
- Quantum Optics
- Ultrafast Science
Background:
- Intense X-ray and extreme ultraviolet (XUV) light sources are established tools.
- Observing Rabi oscillations in the XUV range is experimentally difficult due to weak nonlinear interactions.
Purpose of the Study:
- To propose a novel scheme for detecting XUV-induced Rabi oscillations.
- To enable sensitive monitoring and control of ultrafast nonlinear dynamics in atoms and molecules.
Main Methods:
- Numerical simulations of photoionization in a Helium medium using intense XUV pulses.
- Analysis of superfluorescence (SF) spectra at the He⁺(3p-2s) transition.
- Characterization of Rabi oscillations at the He⁺(1s-3p) transition.
Main Results:
- The proposed scheme demonstrates strong population inversion and Rabi oscillations at the He⁺(1s-3p) transition.
- Significant signatures of XUV-induced Rabi oscillations were identified in the SF spectra.
- The photon energy of 48.36 eV for the XUV pulse was found to induce detectable Rabi oscillations.
Conclusions:
- The suggested method provides a viable pathway to experimentally observe XUV-induced Rabi oscillations.
- The technique offers a sensitive tool for probing and manipulating ultrafast nonlinear phenomena.
- This research advances the understanding of light-matter interactions in the XUV regime.

Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.

2.8K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

1.6K
In Ultraviolet–Visible (UV–Vis) spectroscopy, the absorption of electromagnetic radiation is used to probe the electronic structure of molecules. This technique provides insights into molecular electronic transitions, particularly the movement of electrons between different molecular orbitals. Radiation is absorbed if the energy of the electromagnetic radiation passing through the molecule is precisely equal to the energy difference between the excited and ground states. During this...

5.8K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

Atomic spectroscopy is a vital tool in elemental analysis, both qualitatively and quantitatively. It can be broadly divided into optical spectroscopy, mass spectroscopy, and X-ray spectroscopy methods. The optical spectroscopic methods are atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES), and atomic fluorescence spectroscopy (AFS). The first step in all three methods is atomization, where the solid, liquid, or solution-phase samples are converted into gas-phase atoms and...
