Description
In this work, we present experimental results concerning the laser-driven ion acceleration obtained from the interaction of an ultra-short laser pulse with ultrathin carbon foils. In this interaction regime, laser polarization can play an important role in the ion acceleration, with circular polarization significantly reducing unwanted effects like electron heating and consequently improving the acceleration. Our results show a strong dependence of the maximum ion energies on laser polarisation, with circular polarisation leading to the highest energy values for both carbon ion and proton. This is consistent with the onset of Light Sail acceleration, also indicated by PIC simulations.
