Abstract
Strong stimulated Raman emission has been observed on three Stokes' lines at 1.608, 1.744 and 1.896 μm from 12.6 km of single-mode silica fibre pumped at 1.50 μm with the output of a pulsed barium vapour laser. A study has been made of the spectral distribution of fibre output as a function of peak input power to the fibre (up to 47 MW cm-2), and the results are compared to theoretical predictions. Incomplete conversion of the pump to first Stokes', and first to second Stokes', lines is observed despite the length of the fibre.
