Abstract

Extreme-ultraviolet emission at 65-nm wavelength from xenon nanoclusters irradiated by an intense pulse of soft x rays from a free-electron laser is investigated in a joint experimental-theoretical study. Clear indications of a long-lived population inversion, and subsequent amplified spontaneous emission, are identified.

Evidence of Extreme Ultraviolet Superfluorescence in Xenon

Laurent Mercadier, Andrei Benediktovitch, Clemens Weninger +19 more

We present a comprehensive experimental and theoretical study on superfluorescence in the extreme ultraviolet wavelength regime. Focusing a free-electron laser pulse in a cell filled with Xe gas, the medium is quasi-instantaneously population inverted by 4d-shell ionization on the giant resonance followed by Auger decay. On the timescale of ∼10 ps to ∼100 ps (depending on parameters) a macroscopic polarization builds up in the medium, resulting in superfluorescent emission of several Xe lines in the forward direction. As the number of emitters in the system is increased by either raising the pressure or the pump-pulse energy, the emission yield grows exponentially over four orders of magnitude and reaches saturation. With increasing yield, we observe line broadening, a manifestation of superfluorescence in the spectral domain. Our novel theoretical approach, based on a full quantum treatment of the atomic system and the irradiated field, shows quantitative agreement with the experiment and supports our interpretation.

Observation of Free-Electron-Laser-Induced Collective Spontaneous Emission (Superfluorescence)

Mitsuru Nagasono, James Robert Harries, Hiroshi Iwayama +7 more

We have observed and characterized 501.6 nm collective spontaneous emission (superfluorescence) following 1s(2) → 1s3p excitation of helium atoms by 53.7 nm free-electron laser radiation. Emitted pulse energies of up to 100 nJ are observed, corresponding to a photon number conversion efficiency of up to 10%. We observe the peak intensity to scale as ρ(2) and the emitted pulse width and delay to scale as ρ(-1), where ρ is the atom number density. Emitted pulses as short as 1 ps are observed, which corresponds to a rate around 75,000 times faster than the spontaneous 1s3p → 1s2s decay rate. To our knowledge, this is the first observation of superfluorescence following pumping in the extreme ultraviolet wavelength region, and extension of the technique to the generation of extreme ultraviolet and x-ray superfluorescence pulses should be straightforward by using suitable atomic systems and pump wavelengths.

Observation of extreme ultraviolet superfluorescence from helium atoms ionised and excited using soft x-ray free-electron laser pulses

ハリーズ　ジェームズ, James Harries

We have studied the propagation of free-electron laser pulses at a wavelength of 24.3 nm through a dense sample of helium gas. Ionisation and resonant excitation leads to strong population of the He+ 4p state, and the resulting superfluorescence, yoked superfluorescence, and free-induction decay were observed experimentally. Numerical simulations using the Maxwell-Liouville equations were used to interpret the observations.

Superfluorescence (collective spontaneous emission) observed from helium atoms following excitation using an extreme-ultraviolet free-electron laser

ハリーズ　ジェームズ, ハリーズ ジェームズ

Using numerical simulations, and experiments at a free-electron laser, we have studied superfluorescence emission in helium atoms at visible wavelengths, and also observed strong directional emission at extreme ultraviolet wavelengths.

Amplification of fluorescence from the 3aPo1 doubly excited state in helium

Špela Krušič, K. Bučar, A. Mihelič +1 more

We present a theoretical study of self-amplification of extreme ultraviolet light in a helium gas target. Resonant excitation to the $3a\phantom{\rule{0.16em}{0ex}}^{1}P^{o}$ doubly excited state below the $N=2$ threshold by $100\phantom{\rule{0.28em}{0ex}}\mathrm{fs}$ free-electron laser pulses is followed by fluorescence at $40.7\phantom{\rule{0.28em}{0ex}}\mathrm{eV}$ photon energy. The process is modeled by a three-level atomic system coupled to the continuum and described by the Maxwell-Bloch equations. The evolution of state populations and radiation fields is studied over a wide range of pump intensities and target pressures, clearly showing the regions of spontaneous emission, amplification, and saturation of light emitted in the forward direction. The treatment includes both coherent and SASE pump pulses. In both cases the amplified pulses are temporally coherent and exhibit a duration similar to that of the pump pulses.

Proposal for Observing XUV-Induced Rabi Oscillation Using Superfluorescent Emission

Jun Jie Cui, Yongjun Cheng, Xin Wang +4 more

Intense x-ray and extreme ultraviolet (XUV) light sources have been available for decades, however, due to weak nonlinear interaction in the XUV photon energy range, observation of Rabi oscillation induced by XUV pulse remains a very challenging experimental task. Here we suggest a scheme where photoionization of a He medium by an intense XUV pump pulse is followed by a strong population inversion and Rabi oscillation at the He^{+}(1s-3p) transition and is accompanied by superfluorescence (SF) of the 7.56 eV pulse at the He^{+}(3p-2s) transition. Our numerical simulations show that the Rabi oscillation at the He^{+}(1s-3p) transition induced by an XUV pulse with photon energy 48.36 eV results in significant signatures in the SF spectra, allowing us to identify and characterize the XUV induced Rabi-oscillatory regime. The proposed scheme provides a sensitive tool to monitor and control ultrafast nonlinear dynamics in atoms and molecules triggered by intense XUV.
