报告摘要：

报告首先简要介绍俄罗斯科学院光纤光学中心的研究现状。随后，我们将详细介绍掺铋光纤及其在激光和放大方面的研究成果。

报告回顾并总结了2005年我们在世界上首次研制出的掺铋光纤。为实现掺铋光纤的超宽带荧光和放大特性，有必要对不同组分玻璃纤芯的掺铋光纤进行研究。我们研究了石英玻璃掺铋光纤，氧化锗玻璃掺铋光纤，氧化硅-氧化锗玻璃掺铋光纤，氧化铝-氧化硅玻璃掺铋光纤以及硅磷酸盐玻璃掺铋光纤。通过上述研究，我们在1150nm-1800nm范围内实现了一系列光纤的激光和超宽带光放大。

Abstract:

The presentation will include brief information concerning the Fiber Optics Research Center of the Russian Academy of Sciences. Then the results on the research and development of Bismuth-doped (Bi-doped) optical fibers, Bi-doped fiber lasers and optical amplifiers will be discussed in detail.

The first Bi-doped optical fibers were fabricated by the Fiber Optics Research Center together with the Institute of High-Purity Substances in 2005 using MCVD technique.To create Bi-doped fiber lasers and optical amplifiers operating in broad spectral region it was necessary to use Bi-doped fibers with various core glass compositions. We selected the following fiber core glasses: Bi:SiO2 , Bi:GeO2 , Bi:GeO2-SiO2 , Bi:Al2O3-SiO2,Bi:P2O5-SiO2. In the results, a family of Bi-doped fiber lasers and optical amplifiers operating in the spectral region 1150-1800 nm was developed.
