Recent laser-plasma interaction studies at LLNL

Recent analysis and modeling of Nova experiments which address our understanding of stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) will be presented. Forward and backward SBS levels have been investigated with SSD of varying bandwidth and with polarization smoothing using an f/8 focusing geometry to emulate NIF conditions. The interpretation of the experiments is aided using F3D, a fluid code which includes modeling of SBS and SRS; a parallel version of F3D is being… more

Measurement of local gain and electron density in an yttrium x-ray laser amplifier

X-ray lasers have measured average gains significantly less than calculated and a persistently low level of spatial coherence. We have used an X-ray laser both as an injected signal to a short X-ray laser amplifier and as an interferometer beam to measure two dimensional local gain and density profiles of the X-ray laser plasma with near-1- mm resolution. The measured local gain is in agreement with atomic models, but its gain is unexpectedly spatially inhomogeneous. This inhomogeneity explains… more
