Abstract:

We report an extension of previous table-top soft x-ray laser interferometry work to plasma densities approaching the critical density. The evolution of line-focus and spot-focus plasmas created with Nd-YAG laser intensities of 0.1 and 7.0 TW/cm2 respectively were studied utilizing a 46.9 nm capillary discharge laser with a diffraction grating interferometer. In the later case, the electron density was mapped to values up to 0.9×1021 cm-3 (90% of the critical density for the λ=1.06 μm pump laser). The interferograms show the development of concave electron density profiles with a minimum on axis and pronounced side lobes. Hydrodynamic model simulations show that the concave profile is the result of the hydrodynamic and radiation effects that enlarge the ablated target area. The measurements exemplify how soft x-ray lasers can be used to probe high density plasmas for the validation of hydrodynamic codes.
