“…Besides the intrinsic fundamental interest in investigating this regime in laboratory experiments, RR is often invoked to explain the radiative properties of powerful astrophysical objects, such as pulsars and quasars [11,12]. A detailed characterization of RR is also important for a correct description of high-field experiments using the next generation of multipetawatt laser facilities, such as the Extreme Light Infrastructure [13,14], Apollon [15] [1] and constant over distances of the order of the classical electron radius r 0 ¼ e 2 =4πϵ 0 m e c 2 ≈ 2.8 × 10 −15 m. These conditions are automatically satisfied in classical electrodynamics since quantum effects are negligible as long as the rest frame fields are much smaller than the critical field of quantum electrodynamics (QED) F cr ¼ αF 0 ≈ 1.3 × 10 18 V=m ≪ F 0 [9] and remain constant over distances of the order of the reduced Compton wavelength λ C ¼ r 0 =α ≈ 3.9 × 10 −13 m ≫ r 0 (α ≈ 1=137 is the fine structure constant). An electric field with amplitude of the order of the critical field F cr is able to impart an energy of the order of mc 2 to an electron over a length of the order of λ C .…”

Experimental Signatures of the Quantum Nature of Radiation Reaction in the Field of an Ultraintense Laser

The description of the dynamics of an electron in an external electromagnetic field of arbitrary intensity is one of the most fundamental outstanding problems in electrodynamics. Remarkably, to date, there is no unanimously accepted theoretical solution for ultrahigh intensities and little or no experimental data. The basic challenge is the inclusion of the self-interaction of the electron with the field emitted by the electron itself-the so-called radiation reaction force. We report here on the experimental evidence of strong radiation reaction, in an all-optical experiment, during the propagation of highly relativistic electrons (maximum energy exceeding 2 GeV) through the field of an ultraintense laser (peak intensity of 4 × 10 20 W=cm 2 ). In their own rest frame, the highest-energy electrons experience an electric field as high as one quarter of the critical field of quantum electrodynamics and are seen to lose up to 30% of their kinetic energy during the propagation through the laser field. The experimental data show signatures of quantum effects in the electron dynamics in the external laser field, potentially showing departures from the constant cross field approximation.

“…To drive narrowband TS γ-ray sources, these beams have to meet some minimal requirements, such as a combination of Accelerator Physics -Radiation Safety and Applicationsa near-GeV energy with a percent-scale energy spread, a five-dimensional (5-D) brightness above 10 16 A/m 2 [76], and preferably absent low-energy background. These requirements, in combination with the kHz-scale repetition rate dictated by the applications, are clearly conflicting even for the most ambitious laser technology [77,78]. LPA experiments, guided by the theoretical scaling (2), are presently struggling to reach this level of performance.…”

Thomson scattering (TS) from electron beams produced in laser-plasma accelerators may generate femtosecond pulses of quasi-monochromatic, multi-MeV photons. Scaling laws suggest that reaching the necessary GeV electron energy, with a percent-scale energy spread and five-dimensional brightness over 10 16 A/m 2 , requires acceleration in centimeter-length, tenuous plasmas (n 0 $ 10 17 cm À3 ), with petawatt-class lasers. Ultrahigh per-pulse power mandates single-shot operation, frustrating applications dependent on dosage. To generate high-quality near-GeV beams at a manageable average power (thus affording kHz repetition rate), we propose acceleration in a cavity ofelectrondensity ,drivenwithanincoherent stack of sub-Joule laser pulses through a millimeter-length, dense plasma (n 0 $ 10 19 cm À3). Blue-shifting one stack component by a considerable fraction of the carrier frequency compensates for the frequency red shift imparted by the wake. This avoids catastrophic self-compression of the optical driver and suppresses expansion of the accelerating cavity, avoiding accumulation of a massive low-energy background. In addition, the energy gain doubles compared to the predictions of scaling laws. Head-on collision of the resulting ultrabright beams with another optical pulse produces, via TS, gigawatt γ-ray pulses having a sub-20% bandwidth, over 10 6 photons in a microsteradian observation cone, and the observation cone, and the mean energy tunable up to 16 MeV.

“…During the last 40 years, intensities of laser facilities have been increased from a few KW cm −2 to upper than 10 22 W cm −2 such as the European Extreme Light Infrastructure (ELI) [30], the French Apollon laser [31], the Russian XCELS [32], the U.K. VULCAN laser [33] and the Astra-Gemini at RAL-CLF [34]. Besides the intensity, the average power of a laser is an important parameter.…”

It is known that the linearly polarized photons can partly transform to circularly polarized ones via forward Compton scattering in a background such as the external magnetic field or noncommutative space time. Based on this fact we explore the effects of the NC-background on the scattering of a linearly polarized laser beam from an intense beam of charged leptons. We show that for a muon/electron beam flux ε µ,e ∼ 10 12 /10 10 TeV cm −2 sec −1 and a linearly polarized laser beam with energy k 0 ∼1 eV and average powerP laser 10 3 KW, the generation rate of circularly polarized photons is about R V ∼ 10 4 /sec for noncommutative energy scale Λ NC ∼ 10 TeV. This is fairly large and can grow for more intense beams in near future.
