Influence of Al/Ge ratio on radiation-induced attenuation in nanostructured erbium-doped fibers preforms

Not Accessible

Your library or personal account may give you access

Abstract

We have compared the radiation resistance of various Er3+-doped fiber preforms manufactured with different technologies: Si and Al nanoparticles doped fibers, and standard MCVD fibers. All of them have been irradiated with a total gamma dose of 5.9 kGy and then studied using absorption and EPR spectroscopies.
