Abstract
Optical properties of Tm-doped fibres based on two different host glasses, silica-based and Yttrium-Aluminium-Garnet (YAG) derived, are compared. Crystal-derived fibres (CDF) offer a wider range of core compositions than those made by Modified Chemical Vapor Deposition (MCVD) and offer the ability to tune optical properties towards new applications. Absorption and emission behaviour, including absorption cross-sections, fluorescence intensities and lifetimes of the 3F4 and 3H4 level, are investigated in the wavelength range from 200 to 2100 nm and in a concentration range from 0.08 up to 1.52 mol% Tm2O3.
