摘要：
The effectiveness of incoherence-induced optical smoothing techniques is studied experimentally and good agreement with theory is found. Using incoherent laser-drive radiation, the Rayleigh-Taylor instability is investigated in planar foil targets with imposed sinusoidal modulations. Growth rates of up to 60% of the classical value are inferred from the measurements and the nonlinear behavior of the instability is investigated. Growth is observed at all wavelengths tested between 30 and 100 mum.
