Abstract
The dependence of radiation induced attenuation (RIA) on Al concentrations was investigated for γ-irradiated EDFs doped with different Er, Al and Ge concentrations. The dependence of RIA on dose was found well fitted by power law, and linear dependence of adjusted α on Al concentrations was verified. When the Al concentration was as low as 0.11%, an unknown RIA band with absorption peak around 800 nm was observed, which might be related to Erbium ions.
