Design of a kJ-class HiLASE laser as a driver for inertial fusion energy

High Power Laser Science and Engineering 2014年第2期2卷 1-10页

作者： Antonio Lucianetti Magdalena Sawicka Ondrej Slezak Martin Divoky Jan pilar Venkatesan Jambunathan Stefano Bonora Roman Antipenkov Tomas Mocek HiLASE Project Institute of Physics AS CR Na Slovance 2 18221 Prague Czech Republic CNR-IFN Via Trasea 7 35131 Padova Italy ELI Beamlines Project Institute of Physics AS CR Na Slovance 2 18221 Prague Czech Republic

We present the results of performance modeling of a diode-pumped solid-state HiLASE laser designed for use in inertial fusion energy power plants. The main amplifier concept is based on a He-gas-cooled multi-slab architecture similar to that employed in Mercury laser system. Our modeling quantifies the reduction of thermally induced phase aberrations and average depolarization in Yb3+:YAG slabs by a combination of helium cryogenic cooling and properly designed(doping/width) cladding materials.

Experimental evidence of Bloch surface waves on photonic crystals with thin-film LiNbO_3 as a top layer

引用

光子学研究：英文版 2017年第6期5卷 168-172页

作者： TATIANA KOVALEVICH DJAFFAR BELHARET LAURENT ROBERT MYUN-SIK KIM HANS PETER HERZIG THIERRY GROSJEAN MARIA-pilar BERNAL Département d'Optique P.M.Duffieux Institut FEMTO-ST UMR 6174 CNRS Université Bourgogne Franche-Comté Optics & Photonics Technology Laboratory Ecole Polytechnique Fédérale de Lausanne (EPFL)

Strong nonlinear, electro-optical, and thermo-optical properties of lithium niobate(LN) have gained much attention. However, the implementation of LiNbO_3 in real devices is not a trivial task due to difficulties in manufacturing and handling thin-film LN. In this study, we investigate an optical device where the Bloch surface wave(BSW) propagates on the thin-film LN to unlock its properties. First, access to the LN film from air(or open space) is important to exploit its properties. Second, for sustaining the BSW, one-dimensional photonic crystal(1DPhC) is necessary to be fabricated under the thin-film LN. We consider two material platforms to realize such a device: bulk LN and commercial thin-film LN. Clear reflectance dips observed in far-field measurements demonstrate the propagation of BSWs on top of the LN surface of the designed 1DPhCs.

Refractory hepatic encephalopathy in a patient with hypothyroidism: Another element in ammonia metabolism

Hepatic encephalopathy(HE) remains a diagnosis of exclusion due to the lack of specific signs and symptoms. Refractory HE is an uncommon but serious condition that requires the search of hidden precipitating events(i.e.,portosystemic shunt) and alternative diagnosis. Hypothyroidism shares clinical manifestations with HE and is usually considered within the differential diagnosis of HE. Here,we describe a patient with refractory HE who presented a large portosystemic shunt and post-ablative hypothyroidism. Her cognitive impairment,hyperammonaemia,electroencephalograph alterations,impaired neuropsychological performance,and magnetic resonance imaging and spectroscopy disturbances were highly suggestive of HE,paralleled the course of hypothyroidism and normalized after thyroid hormone replacement. There was no need for intervention over the portosystemic shunt. The case findings support that hypothyroidism may precipitate HE in cirrhotic patients by inducing hyperammonaemia and/or enhancing ammonia brain toxicity. This case led us to consider hypothyroidism not only in the differential diagnosis but also as a precipitating factor of HE.

We studied the influence of antimony on the modification rate of the silicon eutectic with sodium and/or strontium for castiig of A1-Si alloys, and introduced controlled Ca and Sb to the system and studied the resulting compounds, which were determined to be CazSb and A1Sb. Scanning electron microscopy together with the complementary technique of electron backscatter diffraction （EBSD） were used to characterize the materials. The experimental results provided the basis for us to establish that antimony removal from AI occurs mainly through the reaction （Sb）A1 ＋ 2Ca = Ca^Sb ＋ A1.
