“…As a consequence the scattered radiation is chirped and it's spectral lines become much broader, with a number of subsidiary peaks [29,47]. This phenomenon is denoted as ponderomotive broadening [33,[48][49][50].…”

“…(17), describes the spectrum of emitted x-rays for an arbitrarily chirped laser pulse, including the emission of higher harmonics and the effect of ponderomotive broadening due to the gradual slow-down of the electron as it enters the high-intensity regions at the peak of the laser pulse [33,50]. To find the optimal frequency modulation of the initial laser pulse ω(x + ) that compensates the ponderomotive broadening we need an expression for the scattering matrix element where we explicitly see how the slow-down of the electron, which happens on the time-scale of the pulse envelope, affects the shape of the spectral lines of the emitted x-rays.…”

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

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.

“…Thus, it is physically justified to describe the driving field as a pulsed plane wave [7]. This approach has been used recently in connection to not only Thomson and Compton scattering [8][9][10][11][12][13][14][15][16][17][18], but also to other strong-field processes such as * E-mail address: Katarzyna.Krajewska@fuw.edu.pl…”

Supercontinuum and ultrashort-pulse generation from nonlinear Thomson and Compton scattering

2014

Nonlinear Thomson and Compton processes, in which energetic electrons collide with an intense optical pulse, are investigated in the framework of classical and quantum electrodynamics. Spectral modulations of the emitted radiation, appearing as either oscillatory or pulsating structures, are observed and explained. It is shown that both processes generate a bandwidth radiation spanning the range of few MeV, which occurs in a small cone along the propagation direction of the colliding electrons. Most importantly, these broad bandwidth structures are temporarily coherent which proves that Thomson and Compton processes lead to generation of a supercontinuum. It is demonstrated that the radiation from the supercontinuum can be synthesized into zeptosecond (possibly even yoctosecond) pulses. Thus, confirming that Thomson and Compton scattering can be used as novel sources of an ultra-short radiation, opening routes to new physical domains for strong laser physics.
