  We study stimulated Raman scattering (SRS) in laser-fusion conditions with
the Eulerian Vlasov code ELVIS. Back SRS from homogeneous plasmas occurs in
sub-picosecond bursts and far exceeds linear theory. Forward SRS and re-scatter
of back SRS are also observed. The plasma wave frequency downshifts from the
linear dispersion curve, and the electron distribution shows flattening. This
is consistent with trapping and reduces the Landau damping. There is some
acoustic ($\omega\propto k$) activity and possibly electron acoustic scatter.
Kinetic ions do not affect SRS for early times but suppress it later on. SRS
from inhomogeneous plasmas exhibits a kinetic enhancement for long density
scale lengths. More scattering results when the pump propagates to higher as
opposed to lower density.
