Abstract: Ho 3+ doped fluoroaluminate glass fibers based on chemically durable AlF 3 –BaF 2 –YF 3 –PbF 2 –MgF 2 –CaF 2 glasses are fabricated by using a rod-in-tube method. By using an 84 cm long Ho 3+ -doped fluoroaluminate glass fiber as the gain medium and a 1120 nm fiber laser as the pump source, lasing at 2868 nm is obtained, the maximum unsaturated power is about 57 mW for a pump power of 1224 mW, and the corresponding slope efficiency is ~5.1%. The effect of the fiber length on lasing at 2868 nm is also investigated. Our results show that Ho 3+ -doped fluoroaluminate glass fibers are promising gain media for 2.9 µ m laser applications.
