“…Our results significantly extend and improve existing XUV time-domain spectroscopy schemes [9,42] by uniquely combining pathway-selective detection with high phase-stability and high spectral resolution. As such, this work may pave the way for many applications of (non)linear coherent time-domain spectroscopy in the XUV spectral range.…”

The development of schemes for coherent nonlinear time-domain spectroscopy in the extremeultraviolet regime (XUV) has so far been impeded by experimental difficulties that arise at these short wavelengths. In this work we present a novel experimental approach, which facilitates the timing control and phase cycling of XUV pulse sequences produced by harmonic generation in rare gases. The method is demonstrated for the generation and high spectral resolution characterization of narrow-bandwidth harmonics (≈14 eV) in argon and krypton. Our technique simultaneously provides high phase stability and a pathway-selective detection scheme for nonlinear signals -both necessary prerequisites for all types of coherent nonlinear spectroscopy.

“…The harmonic cut-off wavelength varies linearly with increasing laser intensity until the saturation intensity, where harmonic generation stops [64] . As the process of HHG strongly depends on the driving laser field, the harmonics produced have similar temporal and spatial coherence properties, a fact that makes this radiation very appealing for various studies and applications [65][66][67][68][69][70] . The fundamental 800 nm near-infrared (near-IR) laser pulses cannot penetrate plasmas with density higher than around 2 × 10 21 e/cm 3 , while, for example, the 11th harmonic penetrates plasmas at two orders of magnitude higher densities.…”

The rapid development of high intensity laser generated particle and photon secondary sources has attracted widespread interest during the last 20 years not only due to fundamental science research but also because of the important applications of this developing technology. For instance, the generation of relativistic particle beams, betatron-type coherent x-ray radiation and high harmonic generation has attracted the interest from various fields of science and technology due to their diverse applications in biomedical, material science, energy, space, and security applications. In the field of biomedical applications in particular, laser driven particle beams as well as laser driven x-ray sources are a promising field of study. This article looks at the research being performed at the Institute of Plasma Physics & Lasers (IPPL) of the Hellenic Mediterranean University Research Centre. The recent installation of the ZEUS 45 TW laser system developed at IPPL offers unique opportunities for research in laser-driven particle and x-ray sources. This article provides information about the facility and describes initial experiments performed for establishing the baseline platforms for secondary plasma sources.

“…However, despite the improvement in resolution, they require scanning of the objects or reconstructing of the image, which has greatly hindered the real-time imaging ability. On the other hand, the perfect lens was first proposed by Pendry [4] and then the concept of overcoming the diffraction limit (superlens) [5][6][7][8] was demonstrated. An optical superlens can achieve super-resolution imaging by enhancing the evanescent waves.…”

Hyperlensing devices have drawn great attention in recent years due to their ability to amplify the subwavelength image of objects with more detail and information. In this work, a hyperlens with a radian inner surface is designed and demonstrated. The proposed hyperlens is capable of imaging different types of sub-wavelength objects efficiently. Plasmonic resonant cavity is also employed in order to achieve a super-resolution imaging effect. Different objects are investigated to test the performance of the proposed hyperlens. As expected, our hyperlens shows better tolerance than the conventional hyperlensing designs and can achieve imaging resolution down to 60 nm for different types of objects.
