In this paper, recent results obtained on highly
radiative shocks generated in a xenon .lled gas cell using
the GEKKO XII laser facility are presented. Data show extremely high shock velocity (.150 km/s) never achieved
before in gas. Preliminary analyses based on theoretical
dimensionless numbers and numerical simulations suggest
that these radiative shocks reach a new radiative regime
where the radiative pressure plays a role in the dynamics
and structure of the shock. A major effect observed is a
strong anisotropic emission in the downstream gas. This unexpected feature is discussed and compared to available 2D
radiation hydrodynamic simulations.
