    • 3.5-GHz Intra-Burst Repetition Rate Ultrafast Yb-Doped Fiber Laser 

      Kerse, C.; Kalaycioʇlu, H.; Elahi, P.; Akçaalan, Ö.; Ilday, F. Ö. (Elsevier, 2016)
      We report on an all-fiber Yb laser amplifier system with an intra-burst repetition rate of 3.5 GHz. The system is able to produce minimum of 15-ns long bursts containing approximately 50 pulses with a total energy of 215μJ ...
    • All-fiber burst mode laser system integrated with OCT for cataract surgery 

      Kesim D.K.; Kalaycioglu H.; Kerse C.; Ilday F.O. (Institute of Electrical and Electronics Engineers Inc., 2016)
      We demonstrate a burst-mode Yb all-fiber femtosecond laser system integrated with OCT for cataract surgery and aim to enhance further the procedure with lower collateral tissue damage, cleaner, efficient cuts with compact ...
    • All-fiber laser systems that can operate in burst mode 

      Kesim, D. K.; Kalaycioglu, H.; Akçaalan, O.; Ilday, F. O. (OSA - The Optical Society, 2016)
      Fiber lasers which operate in burst-mode where densely spaced pulses occur inside bursts repeated at much lower repetition rates can be valuable tool for sensing and imaging. We introduce such lasers and propose possible ...
    • High-repetition-rate ultrafast fiber lasers for material processing 

      Kalaycıoğlu, H.; Elahi, P.; Akçaalan, Ö.; Ilday, F. Ö. (Institute of Electrical and Electronics Engineers, 2018)
      Ultrafast lasers operating at high repetition rates, in particular the GHz range, enable new possibilities in laser-material processing, particularly accessing the recently demonstrated ablation-cooled regime. We provide ...
    • High-speed, thermal damage-free ablation of brain tissue with femtosecond pulse bursts 

      Kerse, Can; Yavaş, Seydi; Kalaycıoğlu, Hamit; Asik M.D.; Akçaalan, Önder; İlday, F. Ömer (IEEE, 2016)
      We report a novel ultrafast burst mode fiber laser system and results on ablation of rat brain tissue at rates approaching an order of magnitude improvement over previous reports, with no discernible thermal damage. © 2015 IEEE.
    • Tailoring nonlinear temperature profile in laser-material processing 

      Kesim, Denizhan Koray (Bilkent University, 2019-04)
      Ablation cooled material removal opened up great opportunities for understanding nonlinear processes. Especially using lasers as a tool to tailor nonlinear temperature gradient of material and engineering them to achieve ...
    • Ultrafast micromachining of Cu and Si at ultra-high repetition rates with pulse bursts 

      Kerse, Can; Kalaycıoğlu, Hamit; Elahi, Parviz; Yavuz, Koray; Mirza I.; Bulgakova N.M.; İlday, F. Ömer (IEEE, 2016)
      We report a novel ultrafast burst mode fiber laser system, which can deliver pulses at ultra-high repetition rates in order to systematically investigate micromachining efficiency on copper and silicon samples. © 2015 IEEE.
