The formation of ‘radiative shocks’, shocks in which the structure of the density and
temperature is affected by radiation from the shock-heated matter, is ubiquitous in many
astrophysical scenarios. They are present, for instance, in Supernovae remnants, accretion
disks, and in supersonic jets from young stars. The study of these extreme shocks in
controlled laboratory conditions has been possible due to the development of high-power
lasers, which allow producing plasmas with the right physical conditions for radiative
shock formation. I will present results from experiments performed at the Orion (UK) and
PALS (Czech Republic) lasers, in which new geometries have been investigated
particularly the collision between two counterpropagating shocks. The investigation
benefits from the plasma diagnostics available at each laser facility, for instance point-
projection X-ray backlighting and 4-frame optical self-emission imaging at Orion, and
optical laser interferometry with fs-exposure at PALS. The results are also investigated
with numerical simulations using radiation-hydrodynamic codes such as NYM/PETRA and
ARWEN.
