Stimulated Raman scattering suppressors fabricated by femtosecond laser overlap-controlled multilayer line-by-line technology.

Femtosecond-laser-direct-written fiber gratings suffer from excessive scattering and high insertion loss, which restricts their application in fiber laser systems, particularly in the field of high-power lasers. To address this limitation, we propose…
