摘要：
A room-temperature watt-level continuous-wave-output power mid-infrared fiber laser operating at lambda similar to 3 mu m is demonstrated using a Ho3+/Pr3+ co-doped AlF3 based glass fiber as a gain fiber. This fixed-wavelength laser had maximum output power of 1.13 W with a slope efficiency of 10.3% and a long-term operating stability of >40 min without any additional packaging or active thermal management. A fiber laser with tunability from 2.842 to 2.938 Am showed a maximum output power of 110 mW. (C) 2021 Optical Society of America
