  • Title: Luminescence and optical gain in Pb-doped silica-based optical fibers.
    Author: Bufetov IA, Firstov SV, Khopin VF, Abramov AN, Guryanov AN, Dianov EM.
    Journal: Opt Express; 2009 Aug 03; 17(16):13487-92. PubMed ID: 19654756.
    Abstract:
    IR luminescence and optical gain in a Pb-doped fiber have been observed for the first time. Absorption, luminescence and pump on/pump off optical gain spectra, as well as luminescence decay time, have been measured in these fibers. Comparison of optical active center characteristics in Pb-doped and Bi-doped fibers of the same composition indicates an essential difference of optical active centers in these two types of fibers.
