Abstract
Growth rates of the Rayleigh-Taylor instability in foils accelerated with a laser beam smoothed by induced spatial incoherence were measured and compared with hydrodynamic code simulations. Modes with 150- and 100-μm wavelengths grew at predicted rates. However, no growth was experimentally observed at a 50-μm wavelength. Code simulations suggest that induced spatial incoherence can influence the 50-μm Rayleigh-Taylor mode by delaying the start of its growth.Keywords
