Plasma Physics Seminar (Phys 769)

Dr. Richard Berger, Lawrence Livermore National Laboratory
Propagation and Stimulated Scattering of Laser Light at the National Ignition Facility

The 10-20 nanosecond long laser pulse length required to achieve ignition on the National Ignition Facility (NIF) creates long scalelength, hot plasma inside the hohlraum from which stimulated Brillouin and Raman scatter (SBS and SRS) were predicted to be significant energy losses. The predictions were based on simulations that were successful in modeling a number of experiments at the OMEGA laser facility at the Laboratory for Laser Energetics. This talk will review the modeling tools in light of the recent SBS and SRS measurements at NIF.
