    • Vapor deposited Cr-doped ZnS thin films: Towards optically pumped mid-infrared waveguide lasers 

      Karhu, Eric Andrew; Ildstad, Charles Rutherford; Poggio, Stefano; Furtula, Vedran; Tolstik, Nikolai; Sorokina, Irina T; BelBruno, Joseph; Gibson, Ursula (Journal article; Peer reviewed, 2016)
      Compact, affordable mid-IR lasers require the development of gain materials in waveguide form. We report on the high vacuum deposition of Cr:ZnS films with concentration ranging from 1018-1020 dopants/cm3 . At low ...
