“…In our case the radiation spectrum peaks at w w a rad 0 3  while the electron energy a m c 0 e 2  , so that quantum effects are important at a 500 0  . However, the simulations of the hole boring process performed in [64] under conditions quite similar to our case show that using a quantum corrected model of RF leads at most to a 10%  reduction of the conversion efficiency into high-energy radiation, without changing the laser-plasma dynamics qualitatively.…”

Inverse Faraday effect driven by radiation friction

A collective, macroscopic signature to detect radiation friction in laser-plasma experiments is proposed. In the interaction of superintense circularly polarized laser pulses with high density targets, the effective dissipation due to radiative losses allows the absorption of electromagnetic angular momentum, which in turn leads to the generation of a quasistatic axial magnetic field. This peculiar 'inverse Faraday effect' is investigated by analytical modeling and three-dimensional simulations, showing that multi-gigagauss magnetic fields may be generated at laser intensities > -10 W cm 23 2 .

“…These high-energy photons may decay into electron-positron pairs, which will annihilate to produce more photons. [9][10][11] At light intensities above I $ 10 22 W/cm 2 , the field radiated by an electron is sufficiently strong to influence the motion of the electron. In this regime, the electron moves in two significant fields: the original applied field and its own radiated field.…”

Plasmas 20, 113111 (2013); 10.1063/1.4835215Numerical modeling of radiation-dominated and quantum-electrodynamically strong regimes of laser-plasma interaction Phys.When extremely intense lasers (I ! 10 22 W/cm 2 ) interact with plasmas, a significant fraction of the pulse energy is converted into photon emission in the multi-MeV energy range. This emission results in a radiation reaction (RR) force on electrons, which becomes important at ultrahigh intensities. Using three-dimensional particle-in-cell simulations which include a quantum electrodynamics model for the c-photons emission, the corresponding RR force and electron-positron pair creation, the energy partition in the laser-plasma system is investigated. At sufficiently high laser amplitudes, the fraction of laser energy coupled to electrons decreases, while the energy converted to c-photons increases. The interaction becomes an efficient source of c-rays when I > 10 24 W/cm 2 , with up to 40% of the laser energy converted to high-energy photons. A systematic study of energy partition and c-photon emission angle shows the influence of laser intensity and polarization for two plasma conditions: high-density carbon targets and a low-density hydrogen targets. We find that in the opaque region, the laser-to-photon conversion efficiency scales as I 3=2 0

Dense high-energy monoenergetic proton beams are vital for wide applications, thus modern laser-plasmabased ion acceleration methods are aiming to obtain high-energy proton beams with energy spread as low as possible. In this work, we put forward a quantum radiative compression method to post-compress a highly accelerated proton beam and convert it to a dense quasi-monoenergetic one. We find that when the relativistic plasma produced by radiation pressure acceleration collides head-on with an ultraintense laser beam, largeamplitude plasma oscillations are excited due to quantum radiation-reaction and the ponderomotive force, which induce compression of the phase space of protons located in its acceleration phase with negative gradient. Our three-dimensional spin-resolved QED particle-in-cell simulations show that hollow-structure proton beams with a peak energy ∼ GeV, relative energy spread of few percents and number N p ∼ 10 10 (or N p ∼ 10 9 with a 1% energy spread) can be produced in near future laser facilities, which may fulfill the requirements of important applications, such as, for radiography of ultra-thick dense materials, or as injectors of hadron colliders.
