Raman suppression in high-power fiber laser oscillator by long period fiber grating
Results in Physics, 2021 Stimulated Raman scattering (SRS) is a major limiting factor for better performance of high-power fiber lasers. Several spectral filtering methods have been used for Raman suppression, among which long period fiber grating (LPFG) is relatively simple and
