    • 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; Garre Werner, Guillermo (2019-07-01)
      Article
      Accés obert
      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 ...

    • Broad area lasers beam quality improvement using photonic crystals 

      Garre Werner, Guillermo (Universitat Politècnica de Catalunya, 2017-10-27)
      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      Edge-emitting broad area semiconductor lasers (BAL) have a wide range of applications due to their high power, however, are strongly limited by their beam quality. Here, we consider a BAL with an external cavity configuration ...

    • 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
      Accés obert
      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 ...

    • Spatial filtering in edge-emitting lasers by intracavity chirped photonic crystals 

      Gawali, Sandeep Babu; Medina Pardell, Judith; Gailevicius, D.; Purlys, Vytautas; Garre Werner, Guillermo; Cojocaru, Crina; Trull Silvestre, José Francisco; Botey Cumella, Muriel; Herrero Simon, Ramon; Montiel Ponsoda, Joan; Staliunas, Kestutis (2020-10-01)
      Article
      Accés obert
      In this work, we report an experimental and numerical study of the intracavity spatial filtering in edge-emitting lasers using a chirped photonic crystal (PhC) as the filtering element in the near-field domain. We provide ...
