Bismuth-doped optical fibers: a challenging active medium
... Bi22/Bi222, point defects, Bi0 and others have been examined, but none has been directly confirmed to be the defining factor. These hypotheses have been analyzed in detail in Ref. 14. At the same time, the results of extensive research on the luminescence spectra and lasing performance of crystals d ...
