用808 nm激光二极管泵浦铋钽共掺氧化锗玻璃，在室温下观察了玻璃的近红外宽带发射。发射波段覆盖0、E、S、C和L波段（1260 ~ 1625 nm），最大峰近似于1310 nm， FWHM宽度大于400 nm，寿命大于200 lis。观察到的宽带发光归因于玻璃中的铋团簇。铋钽共掺氧化锗玻璃作为宽可调谐激光器和光通信宽带放大器的放大介质，具有广阔的应用前景。(c) 2005年美国光学学会。
Near-infrared broadband emission from bismuth-tantalum-codoped germanium oxide glasses was observed at room temperature when the glasses were pumped by an 808 nm laser diode. The emission band covered the 0, E, S, C, and L bands (1260-1625 nm), with a maximum peak at similar to 1310 nm, a FWHM broader than 400 nm, and a lifetime longer than 200 lis. The observed broadband luminescence was attributed to bismuth clusters in the glasses. Bismuth-tantalum-codoped germanium oxide glass might be promising as amplification media for broadly tunable lasers and wideband amplifiers in optical communications.
