    • All-fiber all-normal dispersion laser with a fiber-based Lyot filter 

      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 ...
    • Burst-mode Yb fiber amplifier producing 30 μJ individual pulse energy 

      Kalaycioǧlu H.; Burak Eldeniz, Y.; Ömer Ilday F.; Eken, K. (2012)
      We report 30-μJ individual pulse energy for 150-ns long amplified bursts of 0.4 mJ total energy from a 1-kHz Yb-fiber amplifier. Non-uniformity of pulse energy distribution inside amplified bursts is significantly reduced. ...
    • Demonstration of cavity-enhanced optical parametric chirped-pulse amplification system at high repetition rate 

      Siddiqui, A.; Hong, K. H.; Moses, J.; Chen, J.; İlday, F. Ö.; Kärtner F. X. (Optical Society of America, 2011-03-28)
      First experimental demonstration of cavity-enhanced OPCPA at 78 MHz with <1 W of pump power is presented. For comparison, we demonstrated saturated gain in a single-pass experiment from 6-W Yb-fiber pump and Er-fiber signal ...
    • Doping management for high-power fiber lasers: 100 W, few-picosecond pulse generation from an all-fiber-integrated amplifier 

      Elahi, P.; Yilmaz, S.; Akçaalan, Ö.; Kalaycioğlu, H.; Öktem, B.; Şenel, Ç.; Ilday, F. Ö.; Eken, K. (Optical Society of America, 2012-07-16)
      Thermal effects, which limit the average power, can be minimized by using low-doped, longer gain fibers, whereas the presence of nonlinear effects requires use of high-doped, shorter fibers to maximize the peak power. We ...
    • 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 ...
    • Pulse fidelity control in a 20-μJ sub-200-fs monolithic Yb-fiber amplifier 

      Fernández, A.; Zhu, L.; Verhoef, A. J.; Sidorov-Biryukov, D.; Pugzlys, A.; Galvanauskas, A.; Ilday, F. Ö.; Baltuška, A. (Pleiades Publishing, 2011-06-04)
      We discuss nonlinearity management versus energy scalability and compressibility in a three-stage monolithic 100-kHz repetition rate Yb-fiber amplifier designed as a driver source for the generation and tunable parametric ...
