Abstract

Narrow line width, high power pulses of optical radiation may be generated by the combination of stimulated emission and stimulated Raman scattering within a rare earth doped optical fibre (24b). The signals of a first (11) and second (13) seed laser sources are coupled into the fiber. The radiation of the pulsed first seed laser source (11) is amplified by stimulated emission of the rare earth ions so that the threshold for stimulated Raman scattering into the mode of the second seed laser source 13 is exceeded, and efficient SRS transfers nearly all the power into the mode seeded by the second seed laser source (13).
