With the advent of multi-petawatt laser systems like the ELI-Beamlines (Czech Republic), APOLLON (France) and SEL (China) the laser-driven ion accelerators will enter the acceleration regimes dominated by radiation pressure. High quality ion beams with low emittance and narrow energy spectrum will be generated when these lasers irradiate tailored targets. Below we present the results of studying the effects of the interface modulations in double layer targets. The numerical particle-in-cell simulations with the code EPOCH [2] are used. We show that the pre-modulated targets can undergo relativistic Rayleigh-Taylor [3] and d Richtmyer-Meshkov instabilities. Their use can improve the properties of generated ion beams.
