ABSTRACT
A saturated XUV laser operating on the J=0-1, 19.6nm transition of Ne-like Germanium provided an excellent source to provide in-line backlighting for 2D imaged radiography. The imprint of a direct drive laser beam and subsequent Rayleigh-Taylor growth of perturbations in a 2μm thick Al foil, irradiated with 0.53μm laser light at 2-8×1012 W/cm2, was investigated. Measurements are presented for the modulation due to random phase plate static speckle, SSD smoothed and ISI smoothed speckle. In addition we present a study of single mode optical imprint generated by the interference pattern of a double rectangular aperture.
