This paper descrlbes the experimental investigation of stimulated Raman scattering obtained from a multimode fiber.10 orders of stimulated Stokes scattering of wavelengths ranging in 546～702 nm have been obtained from a 480m,multimode,low-loss,graded quartz fiber pumped by a 532 nm frequency-doubled YAG:Nd laser beam with a pulse duration of 7 ns,output power of 0.7MW and repetetion rates of 5 and 10 PPS.
