  ABSTRACT: We report a comparative experimental study of the attenuation spectra transformations for a series of Yb doped alumino-germano silicate fibers with different contents of Yb3+ dopants, which arise as the result of irradiation either by a beam of high-energy electrons or by resonant (into the 977-nm absorption peak of YbYb3+ ions) optical pumping. The experimental data obtained reveal that in the two circumstances, substantial and complex but different in appearance changes occur within the resonant absorption band of YbYb3+ ions and in the off-resonance background loss of the fibers. Possible mechanisms responsible for these spectral changes are discussed.
