    • Supercontinuum generation in Mid-IR using Chalcogenide and Germanate Nonlinear Fiber 

      Tolstik, Nikolai; Sorokin, Evgeni; Kalashnikov, Vladimir; Klimentov, Dmitry; Dvoyrin, Vladislav; Sorokina, Irina T (Journal article; Peer reviewed, 2013)
      We demonstrate mid-infrared (mid-IR) supercontinuum generation with bandwidth from 2 to 2.8 μm at 20 dB below the peak in nonlinear step-index chalcogenide fiber using femtosecond mid-IR pulses directly from the oscillator. ...

    • Tm3+-doped CW fiber laser based on a highly GeO2-doped dispersion-shifted fiber 

      Dvoyrin, Vladislav; Sorokina, Irina T; Mashinsky, Valery M.; Ischakova, Lyudmila D.; Dianov, Evgenii M; Kalashnikov, Valdimir L; Yashkov, Mikhail V.; Khopin, Vladimir F.; Guryanov, Aleksey N. (Journal article; Peer reviewed, 2011)
      A novel all-fiber laser based on a highly GeO2-doped dispersion-shifted Tm-codoped fiber, pumped at 1.56 µm wavelength and lasing at 1.862 µm wavelength with a slope efficiency up to 37% was demonstrated. The single-mode ...

    • Yb-Doped Fiber Lasers Operating in the Range of 1147-1200 nm 

      Dvoyrin, Vladislav; Medvedkov, OI; Sorokina, Irina T (Chapter, 2012)
      Pump source brightness and heat production per unit fiber length were found to be the critical parameters for the realized and investigated Yb-doped fiber lasers operating in the range of 1147-1200 nm.

    • Yb-Tm energy transfer in Y-codoped fibers 

      Klimentov, Dmitry; Sorokina, Irina T; Dvoyrin, Vladislav; Halder, Arindam; paul, mukul; Das, Shyamal; Bhadra, Shyamal; Pal, Mrinmay (Chapter, 2013)
      Experimental investigation of Yb-Tm energy transfer process in Yb/Tm-doped fibers with Y-codoping provided a fairly high energy transfer efficiency of 50 %, making lasers based on these glass fibers attractive for diode-pumping ...

    • YDFL Operating in 1150-1200-nm Spectral Domain 

      Dvoyrin, Vladislav; Medvedkov, OI; Sorokina, Irina T (Journal article; Peer reviewed, 2013)
      A family of high-power Yb-doped fiber lasers operated in the range of 1150–1180 nm with output powers of up to 35 W and optical efficiencies up to 60% is realized. Operation at 1200 nm is also demonstrated. Amplified ...
