“…For a 0 > 1, harmonics in the radiation spectrum start to appear, and for a 0 ) 1, the spectrum becomes broad. For linear polarization of the laser, there is also longitudinal motion due to the Lorentz force; therefore, downshifting of the fundamental frequency occurs [24,25]. The monochromatic regime using a relativistic electron bunch has been proposed as a good source for applications [24,[26][27][28].…”

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.

“…The presence of a well defined longitudinal amplitude modulation [24,25] has been introduced to evaluate the distortions on the fundamental and the rise of harmonics. Other approaches consist in evaluating the shift by means of the decrease in velocity of the electron due to the ponderomotive action of the laser field [26], or in calculating numerically the trajectories and inserting them into the classical radiation integral [25,27,28].…”

We analyze the nonlinear classical effects of the X= radiation produced by Thomson/Compton sources. We confirm the development of spectral fringes of the radiation on axis, which comports broadening, shift, and deformation of the spectrum. For the nominal parameters of the SPARC-LAB Thomson scattering and of the European Proposal for the gamma source ELI-NP, however, the radiation, when collected in the suitable acceptance angle, does not reveal many differences from that predicted by the linear model and the nonlinear redshift is subdominant with respect to the quantum recoil. An experiment aimed to the study of the nonlinearities is proposed on the SPARC-LAB source.
