摘要：

The infrared emission of Tm3+/Ho3+-doped antimony-silicate optical fiber has been presented. Luminescence at 2.1 mu m corresponding to I-5(7) -> I-5(8) transition in holmium was obtained by energy transfer between Tm3+ and Ho3+ ions. According to the Forster-Dexter theory, the efficiency of energy transfer of the F-3(4) (Tm3+) -> I-5(7) (Ho3+) transition was calculated. The optimization of the activator content and the donor (Tm3+)/acceptor (Ho3+) ions concentration ratio were conducted with the purpose of maximizing the efficiency of energy transfer. It made possible to select best-suited glass which was used to manufacture double-clad optical fiber. Strong and narrow bands of amplified spontaneous emission which formed as a result of energy transfer between thulium and holmium ions were observed in the fiber under exciting with radiation at 795 nm wavelength.
