Abstract

We have measured modulations imprinted by laser speckle in laser-driven CH2 foils at 10(14) W/cm(2) (laser wavelength 0.53 mu m). We have calibrated the amplitude and Rayleigh-Taylor growth of these modulations with single-mode surface perturbations, converting the imprint to anequivalent surface finish. We examined this imprint for a static speckle pattern and with two different bandwidths on the drive laser. The addition of bandwidth and dispersion to the drive laser reduced the imprinted modulations, with the highest bandwidth showing the largest reduction in imprint, in agreement with LASNEX simulations.
