    • 3.5-W, femtosecond chirped pulse amplification fiber laser system at 1560 nm 

      Elahi, Parviz; Li, Huihui; İlday, Fatih Ömer (IEEE, 2017)
      We report a single-mode, 42 MHz, 3.5-W average power chirped pulse amplification fiber laser system operating at 1560 nm. The laser system comprises a dispersion-managed mode-locked oscillator and twoamplifier stages. The ...
    • 50-W, 1.6-GHz pulse repetition rate from a burst-mode Yb-doped fiber laser 

      Elahi, Parviz; Ertek, A. C.; Eken, K.; İlday, Fatih Ömer (IEEE, 2017)
      We report a 50-W average power Yb-doped fiber laser amplifier system. The laser system produces bursts at a minimum rate of 200 kHz, with 1.6 GHz intraburst repetition rate. The total energy delivers in a burst is 250 μJ ...
    • All-fiber burst mode laser system integrated with OCT for cataract surgery 

      Kesim, D. K.; Kalaycıoğlu, Hamit; Kerse, C.; İlday, Fatih Ömer (IEEE, 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 ...
    • Employing active contours and artificial neural networks in representing ultrasonic range data 

      Altun, Kerem; Barshan, Billur (IEEE, 2008-08)
      Active snake contours and Kohonen's self-organizing feature maps (SOM) are considered for efficient representation and evaluation of the maps of an environment obtained with different ultrasonic arc map (UAM) processing ...
    • Fluence of thulium laser system in skin ablation 

      Bilici, T.; Tabakoğlu, O.; Kalaycıoğlu, Hamit; Kurt, A.; Sennaroglu, A.; Gülsoy, M. (IEEE, 2010)
      Tm:YAP laser system at power levels up to 1.2 W at 1980 nm was established in both continuous-wave and modulated modes of operation. The fluence effect of the laser system for skin ablation was analyzed by histology analysis ...
    • 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.
    • 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.
