英文摘要	A method is proposed to control the stimulated Raman scattering in the inertial confinement fusion by using auxiliary 2 omega light to suppress the stimulated Raman scattering of the 3 omega light. In this scheme, inverse bremsstrahlung absorption and parametric instabilities in the 2 omega light increase the electron temperature and the plasma-density fluctuation, thus preventing the development of Raman scattering of the 3 omega light. This scheme is successfully demonstrated by both one-dimensional kinetic simulations and two-dimensional radiative hydrodynamic simulations. The one-dimensional Vlasov results show that the time-averaged transmissivity of the 3 omega light increases from 0.75 to 0.95 under certain conditions. Results obtained using the particle-in-cell method with Monte Carlo collisions show that the electron temperature is greatly increased with the increasing intensity of the 2 omega light. The two-dimensional radiative hydrodynamic simulation results show that the electron temperature increases from 3.2 keV to 3.5 keV, and the time-averaged backscattering level decreases from 0.28 to 0.1 in the presence of the auxiliary 2 omega light.
