在808nm激光激发下，铋活化m20 - al2o3 - sio2 （M=Li, Na）和li20 - ta2o5 - sio2玻璃在室温下发现了覆盖当前波分复用（WDM）系统整个工作窗口（1260 ~ 1625nm）的宽带近红外发光现象。但铋活化玻璃的近红外发光机理至今仍不清楚。该玻璃的带宽和增益均优于Er3+掺杂硅酸盐玻璃和Ti3+掺杂蓝宝石玻璃，是宽带放大器和宽可调谐激光源的理想增益介质。
New broadband near infrared luminescence covering the whole work windows (1260–1625nm) of the current wavelength division multiplexing (WDM) system was found from bismuth-activated M2O–Al2O3–SiO2(M=Li, Na) and Li2O–Ta2O5–SiO2glasses at room temperature in the case of 808nm-laser excitation. But the near infrared luminescence mechanism of the bismuth-activated glasses is not well understood up to now. The figure-of-merits of bandwidth and gain of the glasses are better than those of Er3+-doped silicate glasses and Ti3+doped sapphire, implying they are the promising gain-medium candidates for the broadband amplifiers and the widely tunable laser sources.
