Abstract

We experimentally and theoretically demonstrated a novel technique to generate a stable multi-wavelength Raman fibre laser (RFL) based on an asymmetrical all-fibre Raman laser cavity by using a broadband chirped fibre Bragg grating (CFBG). The output power variations from detuning the center wavelength of in/out reflectors are studied with symmetrical and asymmetrical RFL cavities. The RFL output with asymmetrical cavity is more stable than that of symmetrical cavity.
