Description
Soft-x-ray laser interferograms of laser-created plasmas generated at moderate irradiation intensities (1x1011-7x1012 W cm-2) with λ=1.06 μm light pulses of ∼13-ns-FWHM (full width at half maximum) duration and narrow focus (∼30 μm) reveal the unexpected formation of an inverted density profile with a density minimum on axis and distinct plasma sidelobes. Model simulations show that this strong two-dimensional hydrodynamic behavior is essentially a universal phenomena that is the result of plasma radiation induced mass ablation and cooling in the areas surrounding the focal spot
