33 Femtosecond Yb-doped optical frequency comb for frequency metrology applications
(Bilkent University, 2013)Optical frequency combs have enabled many applications (high precision spectroscopy, table-top optical frequency metrology, optical atomic clocks, etc.), received considerable attention and a Nobel Prize. In this thesis, ... -
Ablation cooled material removal with bursts of ultrafast pulses
(Bilkent University, 2016-01)Material processing with femto-second pulses allows precise and non-thermal material removal and being widely used in scientific, medical and industrial applications. However, due to low ablation speed at which material ... -
Application of ablation cooling to cataract surgery technique using all-fibre burst-mode laser
(Bilkent University, 2016-01)Cataract is the most common cause of preventable blindness in the world. Each year more than 19 million operations are performed to treat cataract. While history of cataract surgery goes as far as 2000 BC, beginning with ... -
Biophotonic applications of ultrafast fiber lasers: from biomaterial surface modification to sub-cellular nanosurgery
(Bilkent University, 2014)Just a year after the invention of the LASER in 1960, it was demonstrated that lasers could be used for the treatment of certain skin abnormalities. At present, lasers are extensively used in a broad range of medical ... -
Development of femtosecond infrared fiber laser for multiphoton silicon micromachining
(Bilkent University, 2016-09)Femtosecond laser is widely used in material processing. Application of ultrashort lasers makes it possible to process with higher precision compared to picosecond and nanosecond lasers. Moreover, a major challenge in ... -
Engineering the nonlinear dynamics of photonic systems : demonstration of the soliton-similariton fiber laser and nonlinear laser lithography
(Bilkent University, 2013)Nonlinear effects easily and unavoidably arise in ultrafast optics, often acting as sources of limitation to performance. However, many fascinating phenomena, from generation to utilization of ultrashort laser pulses ... -
High power all-fiber laser-amplifier systems for materials processing
(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 ... -
Large-scale solutions of electromagnetics problems using the multilevel fast multipole algorithm and physical optics
(Bilkent University, 2015-04)Integral equations provide full-wave (accurate) solutions of Helmholtz-type electromagnetics problems. The multilevel fast multipole algorithm (MLFMA) discretizes the equations and solves them numerically with O(NLogN) ... -
Prediction and characterisation of intensity noise of ultrafast fiber amplifiers and low noise vibrometer for biological applications
(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 ... -
Repetition-rate stabilization of femtosecond stretched-spectrum fiber laser
(Bilkent University, 2008)Passively modelocked lasers produce trains of femtosecond pulses, with the temporal separation between the pulses being determined by the length of the laser cavity. The repetition rate of the laser is inverse of this ... -
Three dimensional processing of silicon with pulsed lasers for optical applications
(Bilkent University, 2015-05)Micromachining of silicon with lasers is being investigated for the last three decades. Until now, interior silicon modification without inscribing the surface has not resulted in success. Such an ability could enable ... -
Ytterbium doped all-fiber integrated high power laser systems and their applications
(Bilkent University, 2013)For the past decades, high-power laser technology has been developing rapidly all over the world. The scientific interest in fiber lasers stems from the rich nonlinear dynamics. Industrial interest is largely due to their ...
