The proper timing of shocks is essential for inertial confinement fusion ignition targets and to the development of polar direct drive. The effect of the angle of incidence on energy coupling and the production of laser-driven shocks are measured in planar target experiments. Two 100-ps pulses produce a pair of shocks with various strengths and relative delays. Velocity profiles (from VISAR) and self-emission from these shocks are compared to one-dimensional hydrodynamic simulations. A simple refraction model adequately treats the coupling of high-angle beams to the target. This work was supported by the U.S. Department of Energy Office of Inertial Confinement Fusion under Cooperative Agreement No. DE-FC52-92SF19460 and Lawrence Livermore National Laboratory under contract No.W-7405-Eng-48.
