    • All-fiber nonlinearity-and dispersion-managed dissipative soliton nanotube mode-locked laser 

      Zhang Z.; Popa, D.; Wittwer, V. J.; Milana, S.; Hasan, T.; Jiang, Z.; Ferrari, A. C.; Ilday F. Ö. (American Institute of Physics, 2015)
      We report dissipative soliton generation from an Yb-doped all-fiber nonlinearity- and dispersion-managed nanotube mode-locked laser. A simple all-fiber ring cavity exploits a photonic crystal fiber for both nonlinearity ...
    • Generation of Sub-20-fs Pulses From a Graphene Mode-Locked Laser 

      Canbaz, F.; Kakenov, N.; Kocabas, C.; Demirbas, U.; Sennaroglu, A. (OSA - The Optical Society, 2017)
      We demonstrate, what is to our knowledge, the shortest pulses directly generated to date from a solid-state laser, mode locked with a graphene saturable absorber (GSA). In the experiments, a low-threshold diode-pumped ...
    • Graphene-gold supercapacitor as a voltage-controlled saturable absorber for femtosecond pulse generation 

      Baylam, I.; Balci, O.; Kakenov, N.; Kocabas, C.; Sennaroglu, A. (Optical Society of America, 2015)
      We report, for the first time to our knowledge, a voltage-controlled graphene-gold supercapacitor saturable absorber, as a modulator with adjustable insertion loss for low-gain mode-locked lasers. Nearly transform-limited, ...
    • An integrated femtosecond timing distribution system for XFELS 

      Kim, J.; Burnham, J.; Chen, J.; Kärtner, F. X.; Ilday, F. Ö.; Ludwig, F.; Schlarb, H.; Winter, A.; Ferianis, M.; Cheever, D. (Massachusetts Institute of Technology * Research Laboratory of Electronics, 2006)
      Tightly synchronized lasers and RF-systems with timing jitter in the few femtoseconds range are necessary sub-systems for future X-ray free electron laser facilities. In this paper, we present an optical-microwave phase ...
    • 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 ...
