Abstract

In order to study the influence of the initial phase of ultrashort and super elliptically polarized laser on the radiation characteristics of high-energy electrons, the collision model of high-energy electrons and high-energy laser field was constructed by Lorentz equation and electron energy equation, and the numerical simulation was carried out by MATLAB. The data and images of electron trajectory and power and energy distribution of spatial radiation of laser field were obtained. The 3-D radiation characteristics corresponding to different initial laser phases were studied. The results show that when the laser pulse strikes the electron, the electron produces radiation, and the radiation power presents a double peak shape. The radiation power image of high-energy electrons shows symmetrical double peaks when the initial phase is 0°, 180° and 360°. The conclusion provides a certain basis for the study of initial phase 3-D inverse detection of ultrashort and ultra strong elliptically polarized laser.
