Generation of wideband Raman scattering spectra in multimode optical fibres, pumped by an 1.32μm A-O Q-switched Nd:YAG laser, is reported. Discussion shows that the spectra are generated by stimulated Raman scattering and four-photon mixing. Results show that considerable optical continuum is formed because 1.32μm pumping and its Stokes components are near the zero-material-dispersion range of fibers. A new amplification phenomena of the small 1.34μm output of the laser in fibers is observed. It is considered that the amplification comes from the wideband Raman gain of the glass optical fibers.
