Using extensive 2D3V PIC simulations we show that a relativistic Richtmyer-Meshkov like instability results in the generation of collimated quasi-mono-energetic beams of light ions. We compare the e ects of modulations at the surface of single layer targets and at the interface between two di erent particle species of double layer targets. It is shown that initially small perturbations are ampli ed during the laser-target interaction leading to the formation of low-density regions at the positions determined by the initial perturbation geometry and high-density plasma bunches between them. The bunches, with higher density than the density in the initial foil are then accelerated by the laser radiation pressure, leading to the generation of quasi-mono-energetic, collimated ion beams.
