Effect of polarization parameters on electron motion and radiation characteristics under intense laser field

Abstract

With Maxwell equation and Newton equation as a starting point, according to the present situation cannot be directly measuring the parameters of the ultrahigh laser, the theoretical derivation and numerical simulation method is deduced low-energy single electron acceleration model, and through MATLAB iteration, studied and analyzed the different polarization parameters of the laser pulse order electronic movement rule and the characteristics of space radiation. The results show that as the polarization parameterincreases from 0 to 1, the spatial distribution of electron energy radiation changes from linear plane to spiral shape, and the overall trend can be divided into four stages. The trajectory of the electron also changes from the plane oscillation to the spiral, and the radius of the spin gradually increases, and the decreasing speed of the radius after the peak also slows down. Based on the above research, the theoretical and numerical simulation basis is provided for the experimental study of high-energy electron radiation in full time, full space and the anti-detection of various parameters of laser.
