Abstract
Yb3+ doped fluorophosphate (FP/Yb) glasses with emission cross section and fluorescence lifetime as high as 0.8388Ã10â20 cm2 and 2.3 ms were developed, and AlF3 content is proved to decrease the lifetime obviously. Large scale glass casting procedure shows high Tx-Tg doesn't make better casting crystallization stability in certainty. Although Yb laser is difficult to be obtained in FP glass, a 230 mw laser was still achieved from 2 mm thick samples under 976 nm LD excitation because of the large gain parameter(Ïemi à Ïf) of the FP/Yb glass. Lasing test also proved the relationship between laser output and gain parameter. Combined with its wide and flat effective gain property, this FP/Yb glass is a practical new potential material for low power ultra-short pulse application.
