abstract = {A novel regime is proposed where, by employing linearly
polarized laser pulses at intensities 10(21) W cm(-2) (2
orders of magnitude lower than discussed in previous work
[T. Esirkepov et al., Phys. Rev. Lett. 92, 175003 (2004)]),
ions are dominantly accelerated from ultrathin foils by the
radiation pressure and have monoenergetic spectra. In this
regime, ions accelerated from the hole-boring process
quickly catch up with the ions accelerated by target normal
sheath acceleration, and they then join in a single bunch,
undergoing a hybrid light-sail-target normal sheath
acceleration. Under an appropriate coupling condition
between foil thickness, laser intensity, and pulse duration,
laser radiation pressure can be dominant in this hybrid
acceleration. Two-dimensional particle-in-cell simulations
show that 1.26 GeV quasimonoenergetic C6+ beams are obtained
by linearly polarized laser pulses at intensities of 10(21)
W cm(-2).},
