Brief

This article investigates the relationship between the central wavelength of high-power all-fiber superfluorescent sources (SFS) utilizing Yb-doped double-clad fibers and parameters such as pumping power, fiber length, core size, core/clad ratio, and absorption coefficient, finding good agreement between simulations based on steady-state rate equations and experimental results from ten different fibers.

Summary

This paper theoretically and experimentally investigates the central wavelength of high-power all-fiber superfluorescent sources (SFS) using Yb-doped double-clad fibers, revealing its dependence on pumping power and fiber parameters like length, core size, core/clad ratio, and absorption coefficient. The study found good agreement between simulations and experimental results from ten different fibers, demonstrating the potential of SFSs with controllable central wavelengths for applications such as beam combining.
