    • 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 ...
    • Development of a rapid-scan fiber-integrated terahertz spectrometer 

      Keskin, H.; Altan, H.; Yavas, S.; Ilday, F. O.; Eken, K.; Sahin, A. B. (Springer New York LLC, 2014)
      Scientists in terahertz (THz) wave technologies have benefited from the recent developments in ultrafast laser technologies and RF technologies and applied these new gained techniques into characterizing a wide variety of ...
    • High power all-fiber laser-amplifier systems for materials processing 

      Özgören, Kıvanç (Bilkent University, 2011)
      When the fiber lasers first appeared in 1970s, their average powers and pulse energies were so low that they remained as a laboratory curiosity for a long time. The scientific interest in fiber lasers continued due to ...
    • Intracavity optical trapping with fiber laser 

      Kalantarifard, Fatemeh (Bilkent University, 2019-06)
      After Ashkin's seminal works, optical trapping has been a powerful technique for capturing and manipulating sub micro particles not only in physics research fields but also in biology and photonics. Standard optical ...
    • Prediction and characterisation of intensity noise of ultrafast fiber amplifiers and low noise vibrometer for biological applications 

      Gürel, Kutan (Bilkent University, 2013)
      We report on the experimental characterisation and theoretical prediction of intensity fluctuations for ultrafast fibre amplifiers. We formulate a theoretical model with which the intensity noise of a Yb-doped fiber ...
    • Pulse shaping for a long-distance optical synchronization system 

      Ilday, F. O.; Winter, A.; Kärtner, F. X.; Danailov, M. B. (Denshi Jouhou Tsuushin Gakkai, Institute of Electronics Information and Communication Engineer, 2007)
      Next generation free electron lasers aim to generate x-ray pulses with pulse durations down to 30 fs, and possibly even sub-fs. Synchronization of various stages of the accelerator and the probe laser system to the x-ray ...
    • Semi-analytic theory self-similar optical propagation and mode-locking using a shape-adaptive model pulse 

      Jirauschek, C.; Ilday, F. O. (American Physical Society, 2014-01-21)
      A semianalytic theory for the pulse dynamics in similariton amplifiers and lasers is presented, based on a model pulse with adaptive shape. By changing a single parameter, this test function can be continuously tweaked ...
    • Ultra-low noise fiber laser systems and their applications 

      Budunoğlu, İbrahim Levent (Bilkent University, 2014)
      Fiber laser systems are intensely studied for and already utilized in a wide range of scientific, biomedical and industrial applications. Scientifically, fiber lasers are widely used for spectroscopy, laser-matter ...
