We present experiments observing Richtmyer-Meshkov mode coupling and bubble competition in a system arising from wellcharacterized initial conditions and driven by a strong (Mach ~8) shock. These measurements and the analysis method developed to interpret them provide an important step towards the possibility of observing self-similarity under such conditions, as well as a general platform for performing and analyzing hydrodynamic instability experiments. Here, a key feature of these experiments is that the shock is sustained su ciently long that this nonlinear behavior occurs without decay of the shock velocity or other hydrodynamic properties of the system, which facilitates analysis and allows the results to be used in the study of analytic models.
