We consider a linearly polarized frequency-chirped Hermit-Gaussian(0,0) mode laser propagating obliquely with respect to the z-axis. A linear chirp is assumed in which local frequency varies linearly with time and space. The laser interacts with an electron initially at rest located at the origin. Electron motion is investigated through a numerical simulation using a three-dimensional particle trajectory code by solving the relativistic Newton’s equations of motion with corresponding Lorentz force. We find optimum chirp parameter for the maximum electron energy and optimum propagation angle of the laser for the minimum scattering angle of the electron. After the electron attains the final energy, the distance to the z-axis grows slightly when the electron moves along the z-axis which implies that the electron remains restricted near the acceleration direction.
