    • 33-fs Yb-fiber laser comb locked to Cs-atomic clock 

      Şenel, Çağrı; Hamid, R.; Erdoğan, C.; Çelik, M.; Kara, O.; İlday, Fatih Ömer (IEEE, 2013)
      Despite the prevalence of fiber frequency combs around 1.5 μm, few fully stabilized frequency combs have been demonstrated around 1.0 μm, despite the generally superior performance of Yb-fiber lasers compared to Er-fiber ...
    • 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. ...
    • Long-term repetition-frequency stabilization of all-normal-dispersion Yb-doped fiber laser to the cesium standard 

      Ülgüdür, Coşkun; İlday, Ömer Fatih; Hamid, R. (OSA, 2010)
      Repetition-frequency stabilization of a Yb-doped fiber laser to the Cesium standard is reported. Laser amplitude and phase noise is characterized. Performance is limited to 2x10-14 at 100000 averaging time by intrinsic ...
    • 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 ...
    • Sub-50 fs all-fiber Yb-doped laser with anomalous-dispersion photonic crystal fiber 

      Zhang, Zewang; Cenel, C.; Hamid, R.; İlday, F. Ömer (IEEE, 2013)
      An intense research effort has been channelled into improving mode-locked Yb-fiber oscillators in recent years. Despite efforts in all-normal dispersion oscillators, dispersion management is evidently necessary to reach ...
    • Sub-50 fs Yb-doped laser with anomalous-dispersion photonic crystal fiber 

      Zhang, Z.; Şenel, Ç.; Hamid, R.; Ilday, F. Ö. (Optical Society of America, 2013)
      We report on the generation of 42 fs pulses at 1 μm in a completely fiber-integrated format, which are, to the best of our knowledge, the shortest from all-fiber-integrated Yb-doped fiber lasers to date. The ring fiber ...
    • Tailored design of mode-locking dynamics for low-noise frequency-comb generation 

      Şenel, Ç.; Hamid, R.; Erdoǧan, C.; Çelik, M.; İlday, Fatih Ömer (American Physical Society, 2018)
      We report a mode-locked laser design using Yb-doped fiber lasers for low-noise frequency-comb generation. The frequency comb covers the spectral range from 700 to 1400 nm. Although this range is more practical for many ...
