摘　　要：The photobleaching(PB)effect of bismuth active center(BAC)-related silicon(BAC-Si)in the bismuth-and erbium-codoped optical fiber(BEDF)under repeated pumping was studied.The results demonstrated that the irreversible PB could be eliminated after repeated pumping,while the rest of the PB could be decreased and remained stable in the subsequent pumping.The mechanism was also discussed using electron transferring theory and the distribution function concept of activation energy.Moreover,the results also demonstrated that BAC-Si could further become stable,reversible,and irreversible after PB,and new standards can be established for the BEDF to evaluate its quality.
