摘      要：Stimulated Raman scattering(SRS)excited by incoherent light is studied via particle-in-cell *** is shown that a large bandwidth of incoherent light can reduce the growth of SRS and electron heating considerably in the linear ***,different components of the incoherent light can be coupled by the Langmuir waves,so that stimulated Raman backward scattering can *** the bandwidth of incoherent light is larger than the Langmuir wave frequency,forward SRS can be seeded between different components of the incoherent *** incoherent light can only increase the time duration for nonlinear saturation but cannot diminish the saturation level obviously.
