Abstract
The possibility of single-frequency oscillation of a distributed feedback (DFB) Raman fibre laser at modest pump powers was first predicted in Ref. 1, for a 1-m cavity, where it was shown that very strong intensity build-up of the Raman Stokes is expected near the discrete phase shift of the DFB grating. More recently, Raman DFB fibre laser oscillation has been observed [2, 3, 4] in relatively short (12–30cm) DFB cavities.
