In this work we report on the thulium-doped silica-based optical fibers with increased fluorescence lifetime of the 3F4 level thanks to the modification of the local environment of thulium ions by high content of alumina. The determination of the cro

Fluorescence lifetimes of Tm-doped optical fiber preform, elongated preform (cane), fiber and overclad fiber were investigated. The fluorescence lifetime decreased with additional steps of heat treatment, most likely due to diffusion and clustering m

We investigate the influence of various optical fiber fabrication processes on the fluorescence decay of RE ions commonly used in fiber lasers and amplifiers, i.e. Yb3+, Tm3+ and Ho3+. Optical fiber preforms were prepared using the MCVD method combin
