• Recent developments in fiber-based mode-locked lasers have made them increasingly robust
  and flexible. This development trend makes theses lasers more accessible for industrial and
  scientific applications. In this thesis, we describe the construction and characterization of
  a robust and flexible all-polarization-maintaining ytterbium-doped fiber laser, mode-locked
  with a nonlinear amplifying loop mirror. The design of the laser provides robust and easily
  achievable mode-locking. Moreover, our laser includes “tuning knobs” inside the cavity that
  provide a great degree of dynamic flexibility in its operation. We utilized this flexibility
  to implement a novel mechanism for intensity noise suppression and achieve extremely lownoise
  operation. The pump-to-output transfer bandwidth of the laser was also investigated
  theoretically and experimentally in order to understand a trade-off between the bandwidth
  available for active laser stabilization and intensity noise suppression.
