Observation of Rayleigh{endash}Taylor growth to short wavelengths on Nike
Abstract
The uniform and smooth focal profile of the Nike KrF laser [S. Obenschain {ital et al.}, Phys. Plasmas {bold 3}, 2098 (1996)] was used to ablatively accelerate 40 {mu}m thick polystyrene planar targets with pulse shaping to minimize shock heating of the compressed material. The foils had imposed small-amplitude sinusoidal wave perturbations of 60, 30, 20, and 12.5 {mu}m wavelength. The shortest wavelength is near the ablative stabilization cutoff for Rayleigh{endash}Taylor growth. Modification of the saturated wave structure due to random laser imprint was observed. Excellent agreement was found between the two-dimensional simulations and experimental data for most cases where the laser imprint was not dominant. {copyright} {ital 1999 American Institute of Physics.}
