    "abstract": "We present measurements of hard x-rays in the 50-300 keV range from copper\nplasmas produced by 100 fs, 806 nm laser pulses at a peak intensity ~ 1016 W\ncm-2. Surface roughness, even at the tens of nanometer level, is shown to\ninfluence the emission characteristics. The enhanced emission from rough\ntargets is attributed to depolarization of light as well as extra absorption\nfacilitated by the surface irregularities.",
