fibers with holmium ions concentrations in the range from 1000 to 10000 ppm. The fibers were fabricated by the
modified chemical vapor deposition and solution doping method. They were characterized in terms of their spectral
attenuation, refractive index profile, and especially performance in fiber laser. Simultaneously, two different fiber laser
setups were tested. In the first one, holmium-doped fiber in Fabry-Perot configuration was pumping by in house
developed thulium-doped fiber laser in ring arrangement. In the second one, bulk-optic pump-coupling configuration,
consisted of a commercially available thulium fiber laser emitting at 1940 nm and system of lenses and mirrors was used.
We have focused on comparison of laser output powers, slope efficiencies, and laser thresholds for individual holmiumdoped
fiber in these different laser arrangements. Finally, the application of the developed fiber in subpicosecond fiber
laser with graphene-based saturable absorber for mode-locking operation was investigatedWorkplace Institute of Radio Engineering and Electronics Contact Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Year of Publishing 2017
