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

      Oktem, B.; Kalaycioǧlu H.; Ilday F.Ö. (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-fiber Yb-doped laser mode-locked by nanotubes 

      Zhang, U.Z.; Popa, D.; Sun, Z.; Hasan, T.; Ferrari, A.C.; Ilday F.O. (IEEE Computer Society, 2013)
      Single-wall carbon nanotubes (SWNTs) and graphene have emerged as promising saturable absorbers (SAs), due to their broad operation bandwidth and fast recovery times [1-3]. However, Yb-doped fiber lasers mode-locked using ...
    • Microjoule-energy, 1 MHz repetition rate pulses from all-fiber-integrated nonlinear chirped-pulse amplifier 

      Kalaycioglu, H.; Oktem, B.; Şenel, Ç.; Paltani, P. P.; Ilday, F. Ö. (Optical Society of America, 2010-03-23)
      We demonstrate generation of pulses with up to 4 μJ energy at 1 MHz repetition rate through nonlinear chirped-pulse amplification in an entirely fiber-integrated amplifier, seeded by a fiber oscillator. The peak power and ...
    • Micromachining with square-Shaped 1 ns-Long pulses from an all-Fiber Yb-Doped laser-Amplifier system 

      Özgören, K.; Öktem, B.; Ömer Ilday F.; Pasin, E.; Eken, K. (2011)
      We demonstrate micromachining with 1ns-long pulses from an all-fiber laser. Fiber lasers generating uncompressible long pulses have been ignored as undesired operational modes, however their robust, low-repetition-rate ...
