      Pavlov, Ihor; İlbey, Emrah; Dülgergil, Ebru; İlday, Fatih Ömer (Optical Society of America, 2012)
      We demonstrate all-fiber, high-power chirped-pulse-amplifier system, operating at 1550 nm. 156-MHz soliton oscillator seeds a two-stage single-mode amplifier with output power of 10 W. After external compression, pulse ...

      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 ...

      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 ...

      Kesim D.K.; Kalaycioglu H.; Kerse C.; Ilday F.O. (Institute of Electrical and Electronics Engineers Inc., 2016)
      We demonstrate a burst-mode Yb all-fiber femtosecond laser system integrated with OCT for cataract surgery and aim to enhance further the procedure with lower collateral tissue damage, cleaner, efficient cuts with compact ...
    • All-fiber high-energy yb-doped fiber amplifier 

      Oktem, B.; Kalaycioǧlu H.; Ilday F.Ö. (2009)
      We report a robust, all-fiber amplifier seeded by a fiber oscillator. Seed pulses at 1 MHz repetition rate are amplified up to 3 μJ, delivering 1 μJ-energy, 170 fs-long pulses. Duration reduces to 120 fs at 1 μJ amplifier ...

      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 ...
    • Femtosecond laser fabrication of fiber based optofluidic platform for flow cytometry applications 

      Serhatlioglu, M.; Elbuken, C.; Ortac, B.; Solmaz, M. E. (SPIE, 2017)
      Miniaturized optofluidic platforms play an important role in bio-analysis, detection and diagnostic applications. The advantages of such miniaturized devices are extremely low sample requirement, low cost development and ...
    • 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 ...
