Absorption and Emission Properties of Bismuth-Doped Silicate Glass

Abstract:

Single Bi-doped and M/Bi co-doped silicate glass (M=Al, Y, La) were prepared and broadband NIR emission were observed when the glass samples were pumped by 514 nm and 808 nm LD, respectively. The absorption intensity and emission intensity of the Y/Bi co-doped glass and La/Bi co-doped glass decrease obviously compared to single Bi-doped glass. The absorption intensity in the region of 600-1100 nm and the NIR emission intensity pumped by an 808 nm LD were remarkably enhanced by the introduction of Al₂O₃ into the Bi-doped silicate glass. It is suggested that the Al/Bi co-doped silicate glass might be very useful for broadband fiber amplifiers and widely tunable lasers.
