Nonlinearity Engineering of Mode-locked Fiber Lasers: Development of highly stable mode-locked fiber lasers
Physics Department, Bilkent University, Ankara, Turkey
Abstract
Ultrafast science impacts on nearly all areas of modern technology, and
femtosecond lasers are invaluable tools in applications covering diverse fields
such as materials processing, biomedical imaging, and frequency metrology.
Advances in ultrafast science have always gone hand-in-hand with developments
in laser technology and theory. Until recently, fiber lasers have been drawing
interest primarily due to their practical features, such as low cost, robustness,
compactness and high average powers. However, these lasers are also
emerging as highly stable and very low-noise laser sources, with considerable
impact in frequency metrology as well as some impact in accelerator
technologies. Much of the progress in mode-locking theory and development of
new fiber laser oscillators has been channeled into maximizing the energy
extraction, but analysis and understanding of the dynamics of these strongly
nonlinear lasers is lacking in terms of how it affects low-noise operation,
robustness and stability. This talk will focus on our efforts in understanding the
noise generation processes in femtosecond fiber lasers as well as experimental
development of low-noise laser systems.
