    • All-fiber high-energy yb-doped fiber amplifier 

      Öktem, Bülent; Kalaycioǧlu, Hamit; İlday, F. Ömer (IEEE, 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 ...
    • All-normal-dispersion fiber lasers for frequency metrology 

      Şenel, Çağrı; İlday, F. Ömer; Kara, O.; Birlikseven, C.; Erdoǧan, C.; Hamid, R. (Optical Society of America, 2011)
      Development of an all-normal-dispersion Yb-doped fiber laser-based frequency comb is reported. Repetition-frequency stabilization to the cesium standard, amplitude and phase noise measurements indicate low-noise performance. ...
    • Development and characterization of all-normal dispersion fiber laser for frequency comb generation 

      Şenel, Çağrı; İlday, F. Ömer; Kara O.; Hamid, R.; Erdoğan, C. (Optical Society of America, 2011)
      Development of an all-normal-dispersion Yb-doped fiber laser-based frequency comb is reported. Repetition-frequency stabilization to the cesium standard, amplitude and phase noise measurements indicate low-noise performance. ...
    • Fiber amplification of pulse bursts at low repetition rates via synchronous pulsed pumping 

      Kalaycıoğlu,Hamit; Yavaş, Seydi; İlday, F. Ömer; Eken, Koray (Optical Society of AmericaIstanbul Turkey, 2011)
      We report, for the first time, amplification of pulse-bursts in Yb-doped fiber at repetition rates as low as 200 Hz for applications to accelerators and material processing. Synchronous pulsed pumping allows suppression ...
    • 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.
    • Properties of a microjoule-class fiber oscillator mode-locked with a SESAM 

      Lecaplain, C.; Ortac, Bülend; MacHinet G.; Boullet J.; Baumgartl, M.; Schreiber, T.; Cormier, E.; Hideur, A. (IEEE, 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 ...
