“…see Bulanov et al (2015) and literature cited therein). These effects manifest themselves through multi-photon Compton and Breit-Wheeler effects (Nikishov & Ritus 1964a,b;Ritus 1985) (see Narozhnyi & Fofanov (1996), Boca & Florescu (2009), Ehlotzky, Krajewska & Kamiśki (2009), Heinzl, Ilderton & Marklund (2010a), Heinzl, Seipt & Kämpfer (2010b, Mackenroth & Di Piazza (2011), Krajewska & Kamiński (2012), Titov et al (2012), Harvey, Heinzl & Ilderton (2009) for recent studies), i.e. through either photon emission by an electron or positron, or electron-positron pair production by a high energy photon, respectively.…”

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.

“…It should be noted that such intense lasers considering in this study can have nonlinear effects on the Compton scattering in the QED framework [3,4] and consequently in the NCQED [5]. As it is already mentioned the unpolarized nonlinear Compton scattering in the ordinary QED cannot convert the linear polarization to the circular one due to its parity invariance.…”

“…Meanwhile, the Compton scattering of photons from unpolarized electrons is a parity invariant interaction. Consequently, for the primary photons without any circular polarization such a process can not lead to a nonzero circular polarization for the scattered photons because V as a pseudo-scalar quantity cannot be formed from a combination of vectors and scalars [1] [also see [2][3][4][5][6][7]]. In fact, there is no many ways to generate circular polarization in a scattering process in the QED.…”

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.

Narrowband inverse Compton scattering x-ray sources at high laser intensities

et al. 2015

Narrowband x-and gamma-ray sources based on the inverse Compton scattering of laser pulses suffer from a limitation of the allowed laser intensity due to the onset of nonlinear effects that increase their bandwidth. It has been suggested that laser pulses with a suitable frequency modulation could compensate this ponderomotive broadening and reduce the bandwidth of the spectral lines, which would allow to operate narrowband Compton sources in the high-intensity regime. In this paper we, therefore, present the theory of nonlinear Compton scattering in a frequency modulated intense laser pulse. We systematically derive the optimal frequency modulation of the laser pulse from the scattering matrix element of nonlinear Compton scattering, taking into account the electron spin and recoil. We show that, for some particular scattering angle, an optimized frequency modulation completely cancels the ponderomotive broadening for all harmonics of the backscattered light. We also explore how sensitive this compensation depends on the electron beam energy spread and emittance, as well as the laser focusing.
