Abstract

Laser-speckle-seeded modulations in laser-driven targets have been observed with the Nova laser using 0.53 and 0.35 mu m drive. The 0.35 mum drive produced larger modulations (equivalent to 3.3 mu m rms surface finish) than 0.53 mu m drive (2.0 mu m rms). The laser intensity was similar to 10(13) W/cm(2), similar to that suggested for directly driven ignition targets during the first several ns. LASNEX simulations of this thermal smoothing effect in both the rms and spectrum agree with the 0.53 mu m drive data, and are about 15% lower than the measuredresults with 0.35 mu m drive.
