Churkin, D.V.; Vatnik, I.D.; Turitsyn, S.K. and Babin, S.A. Random distributed feedback Raman fiber laser operating in a 1.2 μm wavelength range. Laser Physics, 21 (8), pp. 1525-1529.

Abstract

The random distributed feedback fiber laser operating via the stimulated Raman scattering and random distributed feedback based on the Rayleigh scattering is demonstrated in the 1.2 μm frequency band. The RDFB fiber laser generates at 1174 nm up to 2.4 W of output power with corresponding slope efficiency more than 30%. The output radiation has the spectral shape similar to the conventional Raman fiber lasers and spectral width less than 1.7 nm.
