Effects of laser polarization parameters on the radiation properties of energetic electrons at different initial positions

To investigate the effects of laser pulses with different polarization parameters on the motion and power radiation distribution of high-energy electrons at different initial positions in the laser field, an electron laser collision model is established on the basis of the basic equations of electromagnetism, and the spatial distribution characteristics of the electron oscillating radiation at different initial positions under different polarization parameters are simulated with the help of MATLAB software analysis. It is shown that with the increase of polarization parameter from 0 to 1, the spatial radiation distribution generated by collision with electrons at different positions shows a bimodal transition to the surrounding area; when the initial position is certain, the radiation distribution gradually decreases and flattens with the increase of the polarization parameter; and when the polarization parameter is certain, the radiation distribution shows small changes with the change of the initial position. At the same time, it is found that the maximum value of stereo angle radiation per electron unit space occurs at the polarization parameter of 0.7 with the electrons initially located on the z positive semi-axis at a position 30μm from the origin.
