Notes:
The behavior of stimulated Raman backscattering in an inhomogeneous plasma at subcritical density is investigated in the context of inertial confinement fusion. A refined independent hot spots model has been introduced in a laser interaction postprocessor to hydrodynamical code simulations. The model is shown to reproduce most experimentally observed trends, provided that the Langmuir waves damping is reduced on axis, due to the presence of trapping, inverse bremsstrahlung heating, or perpendicular self-generated magnetic fields. The experiments were carried out at 0.53 μm at the Phébus laser facility, and Raman scattering was measured as a function of laser intensity and relative bandwidth, as well as solid target composition. © 2001 American Institute of Physics.
