Past high-energy density laboratory experiments provided insights into the
physics of supernovae, supernova remnants, and the destruction of interstellar
clouds. In a typical experimental setting, a laser-driven planar blast wave
interacts with a compositionally-homogeneous spherical or cylindrical target.
In this work we propose a new laboratory platform that accounts for curvature
of the impacting shock and density stratification of the target. Both
characteristics reflect the conditions expected to exist shortly after a
supernova explosion in a close binary system. We provide details of a proposed
experimental design (laser drive, target configuration, diagnostic system),
optimized to capture the key properties of recent ejecta-companion interaction
models. Good qualitative agreement found between our experimental models and
their astrophysical counterparts highlights strong potential of the proposed
design to probe details of the ejecta-companion interaction for broad classes
of objects by means of high energy density laboratory experiments.
