摘要
Spectroscopic characterization of fiber preforms fabricated with alkali bismuth gallate (KBG) and fluorophosphate glasses (FP) doped with Ho3+ and Yb3+ are reported. Luminescent properties of the preforms are studied in the near-IR spectral range using 2 W. 975 nm diode laser pumping. Results indicate that both glasses are potentially promising for lasing in the 1.2 mu m and in the 2.2-2.5 mu m spectral range. (c) 2008 Elsevier B.V. All rights reserved.
