Suppression and modification of stimulated Raman scattering in optical fibres by rare-earth doping
Suppression and modification of stimulated Raman scattering in optical fibres by rare-earth doping
Stimulated Raman scattering (SRS) is suppressed in an optical fibre by introducing a loss equivalent to the gain at the Stokes wavelength. The required absorption profile is obtained by doping the fibre with the rare-earth holmium. Experimental measurements on these fibres demonstrate suppression of SRS and an increase in the undepleted intensity levels obtainable in an optical fibre. Moreover suppression of the main Raman band due to silica enables SRS from a weaker phosphorus line at 1.240µm emission to be observed when pumped at 1.064µm.

Abstract
Stimulated Raman scattering (SRS) is suppressed in an optical fibre by introducing a loss equivalent to the gain at the Stokes wavelength. The required absorption profile is obtained by doping the fibre with the rare-earth holmium. Experimental measurements on these fibres demonstrate suppression of SRS and an increase in the undepleted intensity levels obtainable in an optical fibre. Moreover suppression of the main Raman band due to silica enables SRS from a weaker phosphorus line at 1.240µm emission to be observed when pumped at 1.064µm.
