    • All-fiber all-normal dispersion laser with a fiber-based Lyot filter 

      Özgören, K.; Ilday, F. Ö. (Optical Society of America, 2010-04-15)
      We propose the use of a short section of polarization-maintaining fiber as a birefringent medium to construct an all-fiber Lyot filter inside the cavity of a fiber laser. This allows mode-locked operation of an all-fiber ...

    • All-fiber all-normal dispersion laser with an in-fiber Lyot filter 

      Özgören, K.; Ilday F.Ö. (2010)
      We propose use of a short PM-fiber section as birefringent medium to construct an all-fiber Lyot filter, with bandwidth adjustable through the PM-fiber length. An all-fiber all-normaldispersion laser is demonstrated using ...

    • All-fiber nonlinearity-and dispersion-managed dissipative soliton nanotube mode-locked laser 

      Zhang Z.; Popa, D.; Wittwer, V. J.; Milana, S.; Hasan, T.; Jiang, Z.; Ferrari, A. C.; Ilday F. Ö. (American Institute of Physics, 2015)
      We report dissipative soliton generation from an Yb-doped all-fiber nonlinearity- and dispersion-managed nanotube mode-locked laser. A simple all-fiber ring cavity exploits a photonic crystal fiber for both nonlinearity ...

    • All-fiber-integrated soliton-similariton laser with in-line fiber filter 

      Zhang, Z.; Öktem, B.; Ilday, F. Ö. (Optical Society of America, 2012-08-16)
      We demonstrate an all-fiber-integrated Er-doped fiber laser operating in the soliton-similariton mode-locking regime. In the similariton part of the cavity, a self-similarly evolving parabolic pulse with highly linear chirp ...

    • Filterless all-normal dispersion fiber laser 

      Özgören, K.; Ilday, F. Ö. (2009)
      We demonstrate mode-locked operation of an allnormal dispersion Yb-fiber oscillator without the use of bulk bandpass filter. A section of PM-fiber incorporated into the cavity acts as a filter, paving the way towards an ...

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

      Tegin U.; Elahi P.; Senel C.; Ergecen E.; Ilday F.O. (Institute of Electrical and Electronics Engineers Inc., 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 ...

    • Geometric parametric instability of femtosecond pulses in graded-index multimode fiber 

      Teğin, U.; Ortac, B. (OSA - The Optical Society, 2017)
      We numerically and experimentally study the spatio-temporal femtosecond pulse evolution in graded-index multimode fiber at normal dispersion regime. We report the first demonstration of geometric parametric instability ...

    • High-energy femtosecond photonic crystal fiber laser 

      Lecaplain, C.; Ortaç, B.; MacHinet G.; Boullet J.; Baumgart, M.; Schreiber, T.; Cormier, E.; Hideur, A. (2010)
      We report the generation of high-energy high-peak power pulses in an all-normal dispersion fiber laser featuring large-mode-area photonic crystal fibers. The self-starting chirped-pulse fiber oscillator delivers 11 W of ...

    • Observation of soliton molecules with independently evolving phase in a mode-locked fiber laser 

      Ortaç, B.; Zaviyalov, A.; Nielsen, C.K.; Egorov O.; Iliew, R.; Limpert J.; Lederer F.; Tünnermann, A. (2010)
      We report the experimental generation of two-soliton molecules in an all-polarization-maintaining ytterbium-doped fiber laser operating in the normal dispersion regime. These molecules exhibit an independently evolving ...

    • Properties of a microjoule-class fiber oscillator mode-locked with a SESAM 

      Lecaplain, C.; Ortac, B.; MacHinet G.; Boullet J.; Baumgartl, M.; Schreiber, T.; Cormier, E.; Hideur, A. (2011)
      Energy scaling of ultrafast Yb-doped fiber oscillators has experienced rapid progress largely driven by many applications that require high average power femtosecond pulses. The fundamental challenge for ultrafast fiber ...

    • Spatiotemporal instability of femtosecond pulses in graded-index multimode fibers 

      Teǧin, U.; Ortaç, B. (Institute of Electrical and Electronics Engineers Inc., 2017)
      We study the spatiotemporal instability generated by a universal unstable attractor in normal dispersion graded-index multimode fiber for femtosecond pulses for the first time. Experimentally observed spatiotemporal ...
