    • Generation of 1.2-nJ, 62-fs, chirp-free pulses directly from a Yb-doped fiber oscillator 

      Teamir, Tesfay G.; İlday, Fatih Ömer (IEEE, 2016)
      1.2-nJ, 62-fs, linear-chirp-free pulses are generated directly from a mode-locked fiber oscillator through optimized interaction of second- and third-order dispersion with self-phase modulation.
    • Influence of pump noise on mode-locked fiber oscillators 

      Teamir, Tesfay G.; Elahi, Parviz; Budunoğlu, İbrahim Levent; Gürel, Kutan; İlday, Fatih Ömer (OSA, 2015)
      Pump modulation transfer function (MTF), and its dependence on pump power are investigated for all normal dispersion, dispersion managed and soliton-like mode-locked oscillator both in experiment and simulation. We find ...
    • Noise induced creation and annihilation of solitons in dispersion managed fiber oscillators 

      Teamir, Tesfay G.; İlday, Fatih Ömer (SPIE, 2017)
      Optical solitons and their interaction with other solitons or with dispersive wave shed by solitons under modulation instabilities or perturbation constitute a versatile experimental and theoretical platform for studying ...
    • Nonlinear management of fiber oscillator with multiple gain segments 

      Teamir, Tesfay G.; İlday, F. Ömer (Optical Society of America, 2015)
      Strong nonlinear effects typically dominate the dynamics of mode-locked fiber oscillators. These effects are simultaneously sources of fascinatingly rich dynamics and a technological limitation. While most approaches involve ...
    • Nonlinearity management of fiber oscillator with multiple gain segments 

      Teamir, Tesfay G.; İlday, Fatih Ömer (IEEE, 2015)
      Oscillator with two gain segments is used to manage nonlinearity level and distribution. Results suggest that pulse evolution subject to an effective negative nonlinearity arising from complex interaction of gain filtering, ...
    • Nonlinearity management: from fiber oscillators to amplifiers 

      İlday, Fatih Ömer; Şenel, Ç.; Hamid, R.; Teamir, Tesfay G.; Pavlov, Ihor; Teğin, Uğur; Ergeçen, E.; Elahi, Parviz; Iegorov, R. (IEEE, 2016)
      While the standard approach to performance scaling in fiber lasers seeks to reduce nonlinear effects through chirping or mode scaling, I will review recent progress in a complementary approach, whereby the governing dynamics ...
