All-solid antiresonant fiber design for high-efficiency three-level lasing in ytterbium-doped fiber lasers.

The YbARF is designed such that the high-gain wavelengths corresponding to four-level lasing lie in the resonance band characterized by high confinement loss. This enables three-level lasing with high efficiency in a short (0.8-m-long) YbARF, making it a potential candidate for high-peak-power ultrafast lasers at 976 nm. We discuss fiber design considerations and detailed simulation results for three-level lasing performance in the YbARF, which promises >85% lasing efficiency in a single-pass pump configuration. These design concepts can be easily extended to suppress high-gain wavelengths in other rare-earth-doped (e.g., with thulium, erbium, and neodymium) fiber amplifiers or lasers.||URI:||https://hdl.handle.net/10356/156835||ISSN:||0146-9592||DOI:||10.1364/OL.453781||Rights:||© 2022 Optica Publishing Group.
