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

      Senel, C.; Hamid, R.; Erdogan, C.; Celik, M.; Kara, O.; Ilday, F. O. (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-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 ...
    • Sub-50 fs all-fiber Yb-doped laser with anomalous-dispersion photonic crystal fiber 

      Zhang, Z.; Cenel, C.; Hamid, R.; Ilday F.O. (IEEE Computer Society, 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 ...
    • Texturing of titanium (Ti6Al4V) medical implant surfaces with MHz-repetition-rate femtosecond and picosecond Yb-doped fiber lasers 

      Erdoǧan, M.; Öktem, B.; Kalaycioǧlu H.; Yavaş, S.; Mukhopadhyay P.K.; Eken, K.; Özgören, K.; Aykaç, Y.; Tazebay, U.H.; Ilday F.O. (Optical Society of American (OSA), 2011)
      We propose and demonstrate the use of short pulsed fiber lasers in surface texturing using MHz-repetition-rate, microjoule- and sub-microjoule-energy pulses. Texturing of titanium-based (Ti6Al4V) dental implant surfaces ...
