The radiation induced attenuation are reduced compared to standard highly doped fibers. We measured 22% power conversion efficiency for core pumping at 1532nm. %G English %2 https://hal-onera.archives-ouvertes.fr/hal-01070310/document %2 https://hal-onera.archives-ouvertes.fr/hal-01070310/file/DESP14003.1395913161.pdf %L hal-01070310 %U https://hal-onera.archives-ouvertes.fr/hal-01070310 %~ ONERA %~ ONERA-MIP
