  • Beam-combining scheme of high-power broad-area semiconductor lasers with Lyot-filtered reinjection: modeling, simulations, and experiments 

    Brée, Carsten; Raab, Volker; Montiel Ponsoda, Joan; Staliunas, Kestutis (2019-07-01)
    Article
    Restricted access - publisher's policy
    A brightness- and power-scalable polarization beam-combining scheme for high-power, broad-area semiconduc-tor laser diodes is investigated numerically and experimentally. To achieve the beam combining, we employ Lyot-filtered ...
  • Amorphous binary dispersions of chloramphenicol in enantiomeric pure and racemic poly-lactic acid: morphology, molecular relaxations, and controlled drug release

    Article
    Restricted access - publisher's policy
    We study amorphous solid dispersions (ASDs) of the chloramphenicol antibiotic in two biodegradable polylactic acid polymers, namely a commercial sample of enantiomeric pure PLLA and a home-synthesized PDLLA copolymer, to ...
  • On the scaling of uncertainties in thermal hydraulic system codes 

    Casamor Vidal, Max; Martínez Quiroga, Víctor Manuel; Reventós Puigjaner, Francesc Josep; Mendizabal Sanz, Rafael; Freixa Terradas, Jordi (2020-02-01)
    Article

    The present work addresses the scaling e ect on safety margins and uncertainties for best estimate plus uncertainty (BEPU) methodologies. The results of an experiment from the OECD/NEA ROSA-2 project at the LSTF facility ...
  • Two-dimensional repulsive Fermi polarons with short- A nd long-range interactions 

    Bombín Escudero, Raul; Comparin, Tommaso; Bertaina, Gianluca; Mazzanti Castrillejo, Fernando Pablo; Giorgini, Stefano; Boronat Medico, Jordi (American Physical Society (APS), 2019-08-09)
    Article
    Open Access
    We study the repulsive polaron problem in a two-component two-dimensional system of fermionic atoms. We use two different interaction models: a short-range (hard-disk) potential and a dipolar potential. In our approach, ...
  • Photonic crystal spatial filtering in broad aperture diode laser 

    Gawali, Sandeep Babu; Gailevicius, Darius; Garre Werner, Guillermo; Purlys, Vytautas; Cojocaru, Crina; Trull Silvestre, José Francisco; Montiel Ponsoda, Joan; Staliunas, Kestutis (2019-10-02)
    Article
    Restricted access - publisher's policy
    Broad aperture semiconductor lasers usually suffer from low spatial quality of the emitted beams. Due to the highly compact character of such lasers, the use of conventional intracavity spatial filters is problematic. We ...
  • Study of second and third harmonic generation from an indium tin oxide nanolayer: Influence of nonlocal effects and hot electrons 

    Rodríguez Suñé, Laura; Escalora, M.; Johnson, Allan; Cojocaru, Crina; Akozbek, Neset; Coppens, Zachary; Perez Salinas, Daniel; Wall, Simon; Trull Silvestre, José Francisco (2020-01-03)
    Article
    Open Access
    We report comparative experimental and theoretical studies of the second and third harmonic generation from a 20 nm-thick indium tin oxide layer in proximity of the epsilon-near-zero condition. Using a tunable optical ...
  • Interaction of hemispherical blast waves with inhomogeneous spheres: probing the collision of a supernova ejecta with a nearby companion star in the laboratory 

    García Senz, Domingo; Velarde, Pedro; Suzuki Vidal, Francisco; Stehlé, Chantal; Cotelo Ferreiro, Manuel; Portillo García, David; Plewa, Tomasz; Pak, Arthur (Institute of Physics (IOP), 2019-02-01)
    Article
    Open Access
    Past laboratory experiments at high energy density have provided insights into the physics of supernovae, supernovaremnants, and the destruction of interstellar clouds. In a typical experimental setting, a laser-driven ...
  • Ordered and disordered solvates of C 60 and CBrCl 2 H 

    Ye, Jin; Barrio Casado, María del; Céolin, René; Qureshi, Navid; Negrier, Philippe; Rietveld, Ivo B.; Tamarit Mur, José Luis (2019-01-01)
    Article
    Open Access
    The formation of co-crystals is often unexpected; however, the Buckminster fullerene, for which many solvates are known,is an excellent system to study this tendency. In the present paper, C60 and CBrCl2H co-crystals have ...
