    • 33 Femtosecond Yb-doped optical frequency comb for frequency metrology applications 

      Şenel, Çağrı (Bilkent University, 2013)
      Optical frequency combs have enabled many applications (high precision spectroscopy, table-top optical frequency metrology, optical atomic clocks, etc.), received considerable attention and a Nobel Prize. In this thesis, ...
    • 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. ...
    • Influence of modulation of pump and seed signals on fiber amplification of broadband pulses 

      Gürel, Kutan; Elahi, Parviz; Budunoğlu, İbrahim Levent; Şenel, Çağrı; Paltani, Punya Prasanna; İlday, Fatih Ömer (OSA, 2011)
      We report on characterization of the transfer of pump and seed signal modulations, including noise, during fiber amplification. We demonstrate experimentally and theoretically that pump (signal) modulations are transferred ...
    • Influence of pump noise and modulation on in-fiber amplification of broadband pulses 

      Gürel, Kutan; Budunoğlu, İbrahim Levent; Şenel, Çağrı; Paltani, Punya Prasanna; İlday, F. Ömer (Optical Society of America, 2011)
      We investigate experimentally and theoretically the coupling of pump laser modulation and noise fluctuations to the output power of a fiber amplifier for broadband pulse trains using the modulation transfer function approach. ...
