    • Generation of dissipative solitons in normal-dispersion Raman fiber laser 

      Teğin, Uğur; Elahi, Parviz; Şenel, Ç.; Ergeçen, E.; İlday, Fatih Ömer (IEEE, 2016)
      Dissipative soliton pulses in a synchronously pumped all-normal-dispersion Raman fiber laser is presented theoretically and experimentally. The laser generates 7.1 nJ intra-cavity pulses at 1.12 μm and is compressed to 136 fs.
    • High energy dissipative raman soliton laser through XPM stabilization 

      Ergeçen, E.; Tegin, Uğur; Elahi, Parviz; Şenel, Ç.; İlday, F. Ömer (Optical Society of America (OSA), 2015-10)
      Dispersion, nonlinearity and gain determine the intracavity pulse behaviour. We show that pump depletion and XPM play a significant role in the stabilization of high energy dissipative Raman solitons. Using this theoretical ...
    • Optical feedback radiation forces: Intracavity optical trapping with feedback-locked diode lasers 

      Tuna, Yazgan; Sayed, R.; Donato, M.G.; Gucciardi P.G.; Maragò O.M.; Volpe, Giovanni (Optical Society of America, 2012)
      We demonstrate a novel mechanism for optical tweezing, where a trapped particle dynamically alters an external cavity quality factor, reduceing the average intensity and photodamage, even employing low-numerical aperture ...
    • Sub-80 fe dissipative soliton large-mode-area fiber laser 

      Baumgartl, M.; Ortaç, B.; Lecaplain, C.; Hideur, A.; Limpert J.; Tünnermann, A. (2010)
      We report on high-energy ultrashort pulse generation from an all-normal-dispersion large-mode-area fiber laser by exploiting an efficient combination of nonlinear polarization evolution (NPE) and a semiconductor-based ...
    • Ultrashort pulse formation and evolution in mode-locked fiber lasers 

      Baumgartl, M.; Ortaç, B.; Schreiber, T.; Limpert J.; Tünnermann, A. (2011)
      Passive mode-locking in fiber lasers is investigated by numerical and experimental means. A non-distributed scalar model solving the nonlinear Schrödinger equation is implemented to study the starting behavior and intra-cavity ...
