文摘In this report,we start from Lagrange equation and analyze theoretically the electron dynamics in electromagnetic field.By solving the relativistic government equations of electron,the trajectories of an electron in plane laser pulse,focused laser pulse have been given for different initial conditions.The electron trajectory is determined by its initial momentum,the amplitude,spot size and polarization of the laser pulse.The optimum initial momentum of the electron for LSS(laser synchrotron source)is obtained.Linear polarized laser is more advantaged than circular polarized laser for generating harmonic radiation.
