“…The development of compact laser-driven wakefield accelerators (LWFA) [18] provides a well-suited alternative, since it allows GeV electron beams to be generated directly at high power laser laboratories capable of achieving field strengths of a 0 ≫ 1 [19][20][21]. The plausibility of such an experimental approach is evidenced by the observation of nonlinearities in Compton scattering in previous experimental campaigns [22][23][24], motivating the study reported here.…”

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

et al. 2018

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.

“…Several methods have been proposed and implemented to characterize laser intensities, which include the use of multiple tunneling ionization of high Z atoms with high ionization potentials [28][29][30], nonlinear Compton scattering [31,32], and temporally resolved intensity contouring based on a chirped probing scheme [33]. The first method involves the time-of-flight (TOF) detection of multiple ion species produced in the focus of a laser interacting with very low density gases.…”

Characterizing extreme laser intensities by ponderomotive acceleration of protons from rarified gas

et al. 2020

A new method to diagnose extreme laser intensities through measurement of angular and spectral distributions of protons directly accelerated by the laser focused into a rarefied gas is proposed. We simulated a laser pulse focused by an off-axis parabolic mirror by Stratton-Chu integrals, that enables description of laser pulse with different spatial-temporal profiles focusing in a focal spot down to the diffraction limit, that makes our theoretical predictions be a basis for experimental realization. The relationship between characteristics of the proton distributions and parameters of the laser pulse have been analyzed. The analytical and numerical results obtained justify the new method of laser diagnostics. The proposed scheme should be valuable for the commissioning of new extreme intensity laser facilities.

“…Several schemes have been proposed to produce compact γ-rays based on laser-plasma interactions, including laser-driven bremsstrahlung radiation [10][11][12][13][14][15][16] and Compton (or Thomson) scattering [17][18][19][20][21][22][23][24][25][26]. For a laser-driven bremsstrahlung source, where a high-energy electron beam, accelerated in the wakefield induced by an ultrashort and intense laser pulse as it propagates in an underdense plasma, impinges on a target composed of high atomic number (Z) materials, very high-energy (up to 100 MeV) gamma photons can be generated [13][14][15].…”

“…So far the peak brilliance of the γ-ray source (∼10 17 photons s mm mrad 0.1% BW 2 2 ) achieved in this scheme, however, is still low and the conversion efficiency (less than 10 −3 ) is limited by a small cross section although it can be further optimized [16]. The Compton (or Thomson) scattering, based on the collision between a laser-wakefield accelerated electron beam and another counter-propagating laser pulse [17][18][19][20][21][22] or a reflected laser pulse by a plasma mirror [23][24][25][26], has been considered a promising scheme for the production of high-energy high-brilliance γ-rays, since it exploits the double-Doppler upshift of the laser photon energy by relativistic electrons. In this scheme, multi-MeV γ-rays with high peak brilliance (∼10 22 photons s mm mrad 0.1% BW 2 2 ) have already been produced experimentally [26].…”

Highly efficient laser-driven Compton gamma-ray source

et al. 2019

The recent advancement of high-intensity lasers has made all-optical Compton scattering become a promising way to produce ultrashort brilliant γ-rays in an ultra-compact system. However, so far achieved Compton γ-ray sources are limited by low conversion efficiency and spectral intensity. Here we present a highly efficient gamma photon emitter obtained by irradiating a high-intensity laser pulse on a miniature plasma device consisting of a plasma lens and a plasma mirror. This concept exploits strong spatiotemporal laser-shaping process and high-charge electron acceleration process in the plasma lens, as well as an efficient nonlinear Compton scattering process enabled by the plasma mirror. Our full three-dimensional particle-in-cell simulations demonstrate that in this novel scheme, brilliant γ-rays with very high conversion efficiency (higher than 10 −2 ) and spectral intensity (∼10 9 photons 0.1%BW) can be achieved by employing currently available petawatt-class lasers with intensity of 10 21 W cm −2 . Such efficient and intense γ-ray sources would find applications in wide-ranging areas.
