Description
Summary:Mathematical treatment of electron acceleration induced by radially polarized laser pulse in vacuum is presented. Effect of external magnetic field in electron energy is studied. The role of azimuthal magnetic field is found to be important which retain the electron energy only when the acceleration takes place. All the equations are solved by fourth order Runga-Kutta (RK-4) method. It is observed that the electron energy gain increases with the propagation distance in the presence of magnetic field of 5 MG. It is also observed that on increasing the laser intensity, the energy gain increases. For electron trajectory in x-z plane, the behavior of it is similar to a sinusoidal wave but not identical.
