    • Photonic Crystal Microchip Laser 

      Gailevicius, Darius; Koliadenko, Volodymyr; Purlys, Vytautas; Peckus, Martynas; Taranenko, Victor; Staliunas, Kestutis (Macmillan Publishers, 2016-09-29)
      Open Access
      The microchip lasers, being very compact and efficient sources of coherent light, suffer from one serious drawback: low spatial quality of the beam strongly reducing the brightness of emitted radiation. Attempts to improve ...
    • Super-collimation by axisymmetric diffractive metamirror 

      Gailevicius, Darius; Grineviciute, Lina; Peckus, Martynas; Staliunas, Kestutis; Taranenko, Victor (2021-08-05)
      Restricted access - publisher's policy
      We propose and demonstrate experimentally super-collimation of light beams by an axisymmetric diffractive metamirror—an axisymmetric concentric dielectric ring structure positioned in front of a mirror at a distance of ...
