Abstract

We explored that the radiation resistance of erbium-doped fiber (EDF) and bismuth/erbium co-doped fiber (BEDF) through detecting the radiation induced attenuation (RIA) and the fluorescence intensity. Under the radiation of 0-1.5 kGy, the RIA of BEDF is lower than that of EDF, and especially at the radiation doses of 1.5 kGy the difference reaches 2.949 dB/m at 1300nm. In addition, pumped by a 980 nm laser with 1050 mW, the fluorescence intensity of irradiated BEDF at 0.3-1.5 kGy is higher than that of the non-irradiated one, whose tendency is completely different with EDF. Compared with EDF , the RIA is reduced by 57% after the radiation doses of 1.5 kGy, which shows that doping bismuth ion can significantly improve the radiation resistance of EDF.
