摘要：

We report on a double-clad fiber laser operating on the 3P0 -> 3F4 Pr3+ transition (in the deep-red spectral range) pumped by a GaN diode laser at similar to 442 nm. It employs a 0.8-mol% PrF3-doped ZBLAN double-clad fiber with a 7.5-mu m core, a double D-shaped inner cladding, and a length of 3.0 m. The laser delivers a maximum output power of 0.71 W at 716.7 nm with a slope efficiency of 9.0% (versus the launched pump power) and a laser threshold of 0.90 W. The laser emission is partially polarized. The laser performance is simulated providing a guideline for watt-level deep-red fiber laser sources. (c) 2023 Optica Publishing Group
