• Gigahertz Femtosecond Cr:ZnS Laser 

      Tolstik, Nikolai; Evgeni, Sorokin; Sorokina, Irina T. (Chapter, 2014)
      We demonstrate the first Cr:ZnS laser with a gigahertz pulse repetition rate. The passively mode-locked by the graphene-based mirror laser provides 105 mW output power with 180 fs pulse duration and 110 pJ pulse energy.
    • High energy 2.1 micron short-pulsed fiber MOPA laser 

      Skogen, Marius (Master thesis, 2019)
      Denne master oppgaven er sammensatt av flere eksperimenter og numeriske modeller som sammen har ført til utviklingen av en ny kort-pulset, høy energi diode bassert Holmium "Master Oscillator Power Amplifier (MOPA)" laser ...
    • Mode-Locked Thulium-Doped Fiber Laser Based on Highly Ge-Doped Fibers 

      Klimentov, Dmitry; Dvoyrin, V; Sorokina, Irina T. (Chapter, 2014)
      We report SESAM mode-locked, linear cavity thulium-doped fiber laser based on a highly Ge-doped active fiber and operating in the anomalous dispersion regime at 1.88 μm, producing 900-fs pulses amplified up to the 3.7-nJ energy.
    • Optical Coatings as Active Media for Mid-Infrared lasers 

      Karhu, Eric Andrew; Tolstik, Nikolai; Sorokin, Evgeni; Furtula, Vedran; Sorokina, Irina T.; Gibson, Ursula (Chapter, 2016)
      Thin films of Cr and Fe-doped ZnS with high infrared transparency have been deposited by molecular beam epitaxy and show optical properties suitable for use as active media in mid-infrared laser applications.
