Radiation pressure acceleration of thin foils with circularly polarized laser pulses
نویسندگان
چکیده
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 ion accelerators with ultra-short particle bursts.

Stable GeV ion-beam acceleration from thin foils by circularly polarized laser pulses.
A stable relativistic ion acceleration regime for thin foils irradiated by circularly polarized laser pulses is suggested. In this regime, the "light-sail" stage of radiation pressure acceleration for ions is smoothly connected with the initial relativistic "hole-boring" stage, and a defined relationship between laser intensity I0, foil density n{0}, and thickness l{0} should be satisfied. For ...

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 کاملProton Beam Acceleration with Circular Polarized Laser Pulses*
Recently, radiation pressure acceleration (RPA) has been proposed and extensively studied, which shows circularly polarized (CP) laser pulses can accelerate mono-energetic ion bunches in a phase-stableacceleration (PSA) way from ultrathin foils. For appropriate parameters, CP pulses may accelerate foils as a whole with most of the transferred energy carried by ions. It is found that self-organi...
متن کاملRadiation-pressure acceleration of ion beams driven by circularly polarized laser pulses.
We present experimental studies on ion acceleration from ultrathin diamondlike carbon foils irradiated by ultrahigh contrast laser pulses of energy 0.7 J focused to peak intensities of 5x10(19) W/cm2. A reduction in electron heating is observed when the laser polarization is changed from linear to circular, leading to a pronounced peak in the fully ionized carbon spectrum at the optimum foil th...
متن کاملRadiation-pressure acceleration of ion beams from nanofoil targets: the leaky light-sail regime.
A new ion radiation-pressure acceleration regime, the "leaky light sail," is proposed which uses sub-skin-depth nanometer foils irradiated by circularly polarized laser pulses. In the regime, the foil is partially transparent, continuously leaking electrons out along with the transmitted laser field. This feature can be exploited by a multispecies nanofoil configuration to stabilize the acceler...
