Q-switched and mode-locked laser based on aluminium zinc oxide deposited onto D-shape fiber as a saturable absorber

Results in Optics, 2021
In contrast to the direct insertion of a saturable absorber (SA) to fiber laser cavity, the D-shape fiber coated with a SA material introduces more optical non-linearity and SA damage threshold is increased due to the evanescent field light-matter ...
