Time resolved and site-selective spectroscopy of thulium- doped into germano- and alumino-silicate optical fibres and preforms
Optical properties of thulium ions doped in varying concentrations into germano- and alumino-silicate glass fibres and their preforms are studied. Absorption and fluorescence spectra are shown to vary little with thulium concentrations up to 12000 ppm. but vary drastically with germanium or aluminiu...
