A number of theoretical calculations have studied the effect of radiation-reaction forces on radiation distributions in strong-field counterpropagating electron-beam-laser interactions, but could these effects-including quantum corrections-be observed in interactions with realistic bunches and focusing fields, as is hoped in a number of soon-to-be-proposed experiments? We present numerical calculations of the angularly resolved radiation spectrum from an electron bunch with parameters similar to those produced in laser-wakefield-acceleration experiments, interacting with an intense, ultrashort laser pulse. For our parameters, the effect of radiation damping on the angular distribution and energy distribution of photons is not easily discernible for a realistic moderate-emittance electron beam. However, experiments using such a counterpropagating beam-laser geometry should be able to measure these effects using current laser systems through measurement of the electron-beam properties. In addition, the brilliance of this source is very high, with peak spectral brilliance exceeding 10 29 photons s À1 mm À2 mrad À2 ð0:1% bandwidthÞ À1 with an approximately 2% conversion efficiency and with a peak energy of 10 MeV.

“…First, the surface of the RFPM is described by the equation of z = (x 2 + y 2 )/4γf ′ in the laboratory frame. This means that the nominal focal length (γf ′ ) of the RFPM in the laboratory frame is γ times longer than that (f ′ ) in the boost frame [19]. An intense (a 0 =3) fs laser pulse propagating in a plasma medium produces a RFPM and its focal length (γf ′ ) observed in the laboratory frame is about 2 µm.…”

“…As femtosecond high-power laser technology advances [1][2][3], the acceleration of charged particles and the generation of high-energy photons using high-power laser pulses have been extensively investigated [4][5][6]. Much attention has been recently paid to the quantum electrodynamic (QED) phenomena under an ultra-strong laser field (known as the strong field QED (SF QED) [7][8][9]), including vacuum birefringence [10][11][12][13], photon-photon scattering [14][15][16][17][18][19][20][21], and electron-positron pair production via the Schwinger mechanics [22][23][24][25]. An ultra-high laser intensity close to the Schwinger intensity (10 29 W/cm 2 ) is desirable for the QED study.…”

The question of electromagnetic field intensification towards the values typical for strong field Quantum Electrodynamics is of fundamental importance. One of the most promising intensification schemes is based on the relativistic-flying mirror concept, which shows that the electromagnetic radiation reflected by the mirror will be frequency up-shifted by a factor of 4γ 2 (γ is the Lorentz factor of the mirror). In laser-plasma interactions, such a mirror travels with relativistic velocities through plasma and typically has a parabolic form, which is advantageous for light intensification. Thus, a relativistic-flying parabolic mirror reflects the counter-propagating radiation in a form of focused and flying electromagnetic wave with a high frequency. The relativistic-flying motion of the laser focus makes the electric and magnetic field distributions of the focus complicated, and the mathematical expressions describing the field distributions of the focus become of fundamental interest. We present analytical expressions describing the field distribution formed by an ideal flying mirror which has a perfect reflectance over the entire surface and wavelength range. The peak field strength of an incident laser pulse with a center wavelength of λ0 and an effective beam radius of we is enhanced by a factor proportional to γ 3 (we/λ0) in the relativistic limit. Electron-positron pair production is investigated in the context of invariant fields based on the enhanced electromagnetic field. The pair production rate under the relativistic-flying laser focus is modified by the Lorentz γ-factor and the beam radius-wavelength ratio (we/λ0). We show that the electron-positron pairs can be created by colliding two counter-propagating relativistic-flying laser focuses in vacuum, each of which is formed when a 180 TW laser pulse is reflected by a relativistic-flying parabolic mirror with a γ = 12.2.

The multiple colliding laser pulse concept formulated by Bulanov et al. (Phys. Rev. Lett., vol. 104, 2010b, 220404) is beneficial for achieving an extremely high amplitude of coherent electromagnetic field. Since the topology of electric and magnetic fields of multiple colliding laser pulses oscillating in time is far from trivial and the radiation friction effects are significant in the high field limit, the dynamics of charged particles interacting with the multiple colliding laser pulses demonstrates remarkable features corresponding to random walk trajectories, limit circles, attractors, regular patterns and Lévy flights. Under extremely high intensity conditions the nonlinear dissipation mechanism stabilizes the particle motion resulting in the charged particle trajectory being located within narrow regions and in the occurrence of a new class of regular patterns made by the particle ensembles.
