研究了掺铋玻璃作为无色超宽带近红外增益介质的特性。在可控氧化还原条件下制备了无色双掺杂钠-石灰-硅酸盐玻璃，在720nm激发下，在半最大值处实现了全宽约600nm的最宽近红外发射，中心在1000nm处。与所报道的双掺杂玻璃的最短波长相比，发射带向更短的波长延伸。本研究开发的无色双掺杂玻璃具有良好的潜力，可作为宽带增益介质用于放大器和可调谐激光器。
The characteristics of bismuth-doped glasses were investigated as colorless ultrabroadband near-infrared gain media. The colorless Bi-doped soda-lime-silicate glass was prepared under controlled redox conditions, and it realized the broadest near-infrared emission of about 600nm in full width at half maximum, centered at 1000nm, under 720nm excitation. The emission band extended toward shorter wavelengths compared with the shortest wavelength for the Bi-doped glass ever reported. The colorless Bi-doped glass developed in this work has a good potential for the broadband gain media for amplifiers and tunable lasers.
