Abstract
An extensive series of experiments has been conducted on the Nova laser to measure hydrodynamic instabilities in planar foils accelerated by x‐ray ablation. Single‐mode experiments allow a measurement of the fundamental growth rates from the linear well into the nonlinear regime. Two‐mode foils give a first direct observation of mode coupling. Surface‐finish experiments allow a measurement of the evolution of a broad spectrum of random initial modes.
