Characterization of holmium fibers with various concentrations for fiber laser applications around 2.1 microm

Popis výsledku v původním jazyce

In this work, we present experimental results of characterization of the developed holmium-doped silica-based opticalnfibers with holmium ions concentrations in the range from 1000 to 10000 ppm. The fibers were fabricated by thenmodified chemical vapor deposition and solution doping method. They were characterized in terms of their spectralnattenuation, refractive index profile, and especially performance in fiber laser. Simultaneously, two different fiber lasernsetups were tested. In the first one, holmium-doped fiber in Fabry-Perot configuration was pumping by in housendeveloped thulium-doped fiber laser in ring arrangement. In the second one, bulk-optic pump-coupling configuration,nconsisted of a commercially available thulium fiber laser emitting at 1940 nm and system of lenses and mirrors was used.nWe have focused on comparison of laser output powers, slope efficiencies, and laser thresholds for individual holmiumdopednfiber in these different laser arrangements. Finally, the application of the developed fiber in subpicosecond fibernlaser with graphene-based saturable absorber for mode-locking operation was investigated
