Ho3+/Pr3+ co-doped AlF3-based glass fibers were fabricated by using a rod-in-tube method based on the matrix glass composition of AlF3 - BaF2 - CaF2 - YF3 - SrF2 - MgF2 - LiF - ZrF4 - PbF2. Under the pump of a 1150 mW Raman fiber laser, a 2.9 mu m laser was observed in a 19 cm long Ho3+/Pr3+ co-doped AlF3-based glass fiber with an output power of 173 mW and a slope efficiency of 10.4%. Ho3+/Pr3+ co-doped AlF3-based glasses were fabricated to investigate the deactivation effects of Pr3+ ions on the Ho3+ : I-5(7) level. Our results showed that the Ho3+/Pr3+ co-doped AlF3-based glass fibers are potential gain media for similar to 2.9 mu m lasers. (C) 2020 Optical Society of America
