Abstract
The acceleration of ions from ultrathin (10–100 nm) carbon foils has been investigated using intense
(∼6 × 1020 W cm−2) ultrashort (45 fs) laser pulses, highlighting a strong dependence of the ion beam
parameters on the laser polarization, with circularly polarized (CP) pulses producing the highest energies
for both protons and carbons (25 − 30 MeV=nucleon); in particular, carbon ion energies obtained
employing CP pulses were significantly higher (∼2.5 times) than for irradiations employing linearly
polarized pulses. Particle-in-cell simulations indicate that radiation pressure acceleration becomes the
dominant mechanism for the thinnest targets and CP pulses.
