Abstract
A new type of fibre Raman laser composed of a GeO2- and P2O5-doped silica fibre was investigated experimentally and theoretically. The output of the laser displays two difference characteristics depending on the type of fibre being used as the input end. Using the P2O5-doped fibre as the input end, the Raman Stokes line of 1320cm−1 shift was enhanced by the latter GeO2-doped fibre. While the GeO2-doped fibre used as the input end, a wideband continuous spectrum was obtained. A model including effects of bandwidth of the Raman gain, four-wave mixing and the mutual influence of the GeO2- and P2O5-doped silica fibre was constructed to illustrate the experimental observation.
