Abstract

The radiation resistance of Yb-doped fiber lasers, especially regarding Yb fiber lasers varying in doping constituents and at different doping concentrations is largely unknown. This paper reports on the gamma-ray induced optical transmission responses of two identical optical fibers that differed in their Yb doping concentrations by two orders of magnitude. The relative amplified spontaneous emission and insertion loss measurements of the two Yb fibers lasers is examined following irradiation by gamma-ray photons with energies of 1.17 and 1.33 MeV. The fibers were observed to exhibit excellent radiation resistance to gammarays following irradiations performed at a nominal dose rate of 2.1 rad(Si) s^-1 and to a total dose of approximately 97.1 krad(Si). Comparisons of irradiated Yb fiber responses with other reported irradiated Yb doped fibers is presented.
