A room-temperature watt-level CW-output power mid-infrared multimode fiber laser operating at λ~3 μm 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 minutes without any additional packaging or active thermal management. A fiber laser with tunability from 2.842 to 2.938 μm showed a maximum output power of 110 mW.

Abstract

A room-temperature watt-level CW-output power mid-infrared multimode fiber laser operating at λ~3 μm 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 minutes without any additional packaging or active thermal management. A fiber laser with tunability from 2.842 to 2.938 μm showed a maximum output power of 110 mW.
