    • Amplitude noise of femtosecond fiber lasers in different modelocking regimes 

      Budunoğlu, İbrahim Levent; İlday, Fatih Ömer (OSA, 2007)
      Amplitude noise of femtosecond fiber laser oscillators are characterized in soliton, similariton, stretched-pulse and all-normal GVD regimes of mode-locking. Integrated relative intensity noise as low as 0.023% (1 Hz-100 ...
    • Characterization of coupling of pump fluctuations to laser in mode-locked Yb-doped and Er-doped fiber oscillators 

      Budunoğlu, İbrahim Levent; Gürel, Kutan; İlday, F. Ömer (Optical Society of America, 2010)
      Transfer of fluctuations of pump power to laser power is characterized for mode-locked fiber oscillators. Contribution of pump noise to laser noise is estimated. Limits to pump modulation bandwidth for carrier-envelopephase ...
    • 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. ...
    • Influence of pump noise on mode-locked fiber oscillators 

      Teamir, Tesfay G.; Elahi, Parviz; Budunoğlu, İbrahim Levent; Gürel, Kutan; İlday, Fatih Ömer (OSA, 2015)
      Pump modulation transfer function (MTF), and its dependence on pump power are investigated for all normal dispersion, dispersion managed and soliton-like mode-locked oscillator both in experiment and simulation. We find ...
    • Ultra-low noise fiber laser systems and their applications 

      Budunoğlu, İbrahim Levent (Bilkent University, 2014)
      Fiber laser systems are intensely studied for and already utilized in a wide range of scientific, biomedical and industrial applications. Scientifically, fiber lasers are widely used for spectroscopy, laser-matter ...
