    • Femtosecond laser crystallization of amorphous Ge 

      Salihoglu, O.; Kürüm, U.; Yaglıoglu, G. H.; Elmali, A.; Aydınlı, Atilla (American Institute of Physics, 2011)
      Ultrafast crystallization of amorphous germanium (a-Ge) in ambient has been studied. Plasma enhanced chemical vapor deposition grown a-Ge was irradiated with single femtosecond laser pulses of various durations with a range ...
    • Fiber laser-microscope system for femtosecond photodisruption of biological samples 

      Yavaş, Seydi; Erdoğan, Mutlu; Gürel, Kutan; İlday, F. Ömer; Eldeniz, Y. B.; Tazebay, Uygar H. (Optical Society of America, 2012-02-22)
      We report on the development of a ultrafast fiber lasermicroscope system for femtosecond photodisruption of biological targets. A mode-locked Yb-fiber laser oscillator generates few-nJ pulses at 32.7 MHz repetition rate, ...
    • 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.
    • Microfluidic measurement of erythrocyte sedimentation rate and monitoring of erytrocyte aggregation 

      Isiksacan, Ziya; Elbuken, Çağlar (Chemical and Biological Microsystems Society, 2016)
      We developed a novel microfluidic opto-electro-mechanical system and performed ultrafast, cheap, and low-sample volume measurement of erythrocyte sedimentation rate (ESR) from erythrocyte aggregation (EA). We also showed ...
    • Properties of a microjoule-class fiber oscillator mode-locked with a SESAM 

      Lecaplain, C.; Ortac, Bülend; MacHinet G.; Boullet J.; Baumgartl, M.; Schreiber, T.; Cormier, E.; Hideur, A. (IEEE, 2011)
      Energy scaling of ultrafast Yb-doped fiber oscillators has experienced rapid progress largely driven by many applications that require high average power femtosecond pulses. The fundamental challenge for ultrafast fiber ...
    • Repetition rate tuning of an ultrafast ytterbium doped fiber laser for terahertz time-domain spectroscopy 

      Keskin H.; Altan H.; Yavaş, Seydi; İlday, F. Ömer; Yagci, M.E.; Aydin O.; Eken, K.; Sahin, B. (IEEE, 2013)
      Repetition rate tuning enables the fast acquisition of THz pulse profiles [1]. By using this method we demonstrate a compact and broadband terahertz time domain spectroscopy system (THz TDS) driven by ytterbium doped fiber ...
    • 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.
