Abstract By using a pulsed dye Laser of nanosecond level as a pomp source, we have investigated stimulated Raman scattering and stimulated four-photon mixing in Er3+ doped silica fibers. The experimental results show that all lines, including the pump radiation line, are obviously broadened and the anti-Stokes lines of stimulated four-photon mixing arc greatly enhanced, and that the enhancement effect is independent of the wavelength.
