Interaction of explosively driven dense plasmas with a low-intensity laser radiation

The results of first experiments on reflectivity of polarized light on an explosively driven dense xenon plasma are presented. The study of polarized reflectivity properties of the plasma was accomplished using a laser light of wavelength λ = 1064 nm and at incident angles θ = 0–30°. With density ρ = 2.7 g cm−3, pressure P = 10.5 GPa and temperatures up to T ~ 3104 K of the investigated plasma, conditions with strong Coulomb interaction (the nonideality parameter up to Г ~ 2.0) were present. Reflectivities, which were calculated via the Helmholtz equation incorporating a density profile for the plasma surface, are compared to the experimental results.
