Space characteristics of nonlinear Thomson scattering with different chirped parameters

In this paper, the motion trajectories, radiation spatial distribution, time spectrum and spectrum distribution of electrons during the interaction between circularly polarized pulses with different chirps are studied. The motion state and radiation distribution during electron and pulse interaction were calculated and obtained by 4-5Runge-Kutta- Fehlberg method (RKF45). The visualization of motion trajectory and radiation distribution is realized by data fitting and MATLAB simulation. The effects of chirp parameters on the radial contraction of electron trajectory, the increase of peak radiation power, the adjustment of peak radiation generation time, and the vortex coupling of radiation spatial distribution are studied. In general, this paper provides an important reference for further understanding and application of chirped pulses in optics and physics by deeply studying the characteristics of electrons under different conditions of Gaussian circularly polarized laser chirped pulses.
