Paper Abstract

In this paper we present experimental results of characterization of the experimentally prepared thulium-doped optical fibers in double-clad hexagonal fiber geometry for cladding optical pumping at a wavelength of 793 nanometers. The fiber was fabricated by the modified chemical vapor deposition and solution doping method and coated with polymer with lower refractive index than silica. The fiber was characterized in views of its refractive index profiles, thulium ions concentration, spectral absorptions, fluorescence lifetime, and performance in fiber laser.
