Radiation pressure acceleration of thin foils with circularly polarized laser pulses
A new regime is described for radiation pressure acceleration of a thin foil by an intense laser beam of above 1020 W cm. Highly monoenergetic proton beams extending to giga-electron-volt energies can be produced with very high efficiency using circularly polarized light. The proton beams have a very small divergence angle (<4). This new method allows the construction of ultracompact proton and...
متن کاملIssues in Radiation Pressure Acceleration
Radiation Pressure Acceleration by circularly polarized laser pulses has been proposed and widely investigated theoretically as a promising scheme for efficient generation of ions. In particular, the use of ultrathin targets may allow to reach energies per nucleon beyond the GeV range. The first, recently reported experiments appear to confirm the basic mechanism and i...
متن کاملPolarization Dependence of Bulk Ion Acceleration from Ultrathin Foils Irradiated by High-Intensity Ultrashort Laser Pulses.
The acceleration of ions from ultrathin (10-100 nm) carbon foils has been investigated using intense (∼6×10^{20} 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 energi...
متن کاملEnhanced laser-ion acceleration in thin foils of reduced surface
Ion acceleration in the interaction of ultrashort intense laser pulses (~ 2×10 W/cm, 10s-100s fs) with thin solid foils of limited transverse extend (~ 10s of μm) is measured experimentally and studied numerically (by PIC simulations). Reducing the target surface area allows hot electrons to be reflected from target edges during or shortly after the laser pulse. This transverse refluxing in suc...
متن کاملWakefield Acceleration by Radiation Pressure in Relativistic Shock Waves
A particle acceleration mechanism by radiation pressure of precursor waves in a relativistic shock is studied. For a relativistic, perpendicular shock with the upstream bulk Lorentz factor of γ1 ≫ 1, large amplitude electromagnetic (light) waves are known to be excited in the shock front due to the synchrotron maser instability, and those waves can propagate towards upstream as precursor waves....
