Document Type and Number:
WIPO Patent Application WO/2018/212631
Kind Code:
A2
Abstract:
Fluorophosphate-based glass for an active element, disclosed herein, comprises: a metaphosphate composition comprising Al(PO3)3; a fluoride composition comprising BaF2 and SrF2; and a dopant provided with ErF3 and YbF3. The fluorophosphate-based glass has thermal and mechanical properties allowing the adoption thereof as a base glass material for an active element (e.g., an optical fiber laser), has the characteristics of a high-fluorescence cross section, and has reinforced down- and up-conversion emission characteristics, and a high sensitivity (S) in an extremely low temperature environment.
