• Emission decay and energy transfer in Yb/Tm Y-codoped fibers based on nano-modified glass 

      Klimentov, Dmitry; Dvoyrin, Vladislav; Halder, Arindam; Paul, Mukul Chandra; Das, Shyamal; Bhadra, Shyamal K; Sorokina, Irina T (Journal article, 2015)
      We report the results of an experimental investigation and theoretical analysis of luminescence decay in Yb/Tm Y-codoped fibers based on nano-modified glass. Based on the experimental results, numerical simulations allowed ...
    • Novel Y2O3-codoped Yb/Tm-doped picosecond fiber laser 

      Dvoyrin, Vladislav; Klimentov, Dmitry; Halder, Arindam; Mukul C, Paul; Mrinmay, Pal; Bhadra, Shyamal K; Kir'yanov, Alexander; Sorokina, Irina T (Journal article; Peer reviewed, 2013)
      We demonstrate the novel picosecond mode-locked Y2O3-codoped Yb/Tm-doped fiber lasers, operating at 1950 nm and producing pulses of up to 1 nJ energy, using a SESAM and an Er-doped pump fiber laser operating at the wavelength ...
    • 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 ...
