Abstract
Ruby-laser light scattering was used to gain spatially and temporally resolved information about plasma parameters for nanosecond CO2 laser-plasma interaction studies. The results confirm a heating model, where heat conduction in dense model plasmas can be described classically. CO2-laser excited stimulated Brillouin scattering could directly be shown to arise from near thermal level by simultaneous Thomson scattering with a ruby-laser, and turbulence enhanced density fluctuations could be excluded.
