摘      要：We discuss stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) under the convective instability condition with a one-dimensional three-wave interaction (3WI) *** linear theory,we deduce the temporal growth rate,gain exponent,and reflectivity of the backward scattered wave in a finite interaction *** find that the growth rate is not only determined by the laser intensity and plasma density and temperature,but also related to the spatial *** length of the interaction region is important to the gain exponent and backscattering *** simulate the developments and evolutions of SRS and SBS based on the 3WI *** numerical results consist with the linear theory.
