摘要: When the input irradiance I exceeds a threshold value, two mechanisms cause stimulated Raman scattering by plasma to increase as exp(g/sub E/I/sup 2/chi). One mechanism is nonlinear in plasmon amplitude, and other second-order process of converting laser photons into Stokes photon an anti-Stokes photon. In fusion, enhanced residual fusion-chamber gas may greatly reduce at target. This theoretical possibility should be investigated experimentally.
