OPTICAL FIBER DEVICES AND METHODS FOR REDUCING STIMULATED RAMAN SCATTERING (SRS) LIGHT EMISSIONS FROM A RESONANT CAVITY

Abstract: fiber laser devices, systems, and methods for reducing raman spectrum in emissions from a resonant cavity. a fiber laser oscillator that is to generate an optical beam may include a raman reflecting output coupler that strongly reflects a raman component pumped within the resonant cavity, and partially reflects a signal component to sustain the oscillator and emit a signal that has a reduced raman component. a raman filtering output coupler may comprise a superstructure fiber grating, and such a grating may be chirped or otherwise designed to have a desired bandwidth.
