Applications such as electron microscopy or the free-electron laser require electron beams with a narrow distribution of the kinetic energy. In order to control the width of this distribution, we suggest to scatter electrons off two counterpropagating light waves, that is we utilize induced Compton scattering. Within a description based on classical mechanics we have found the optimal parameters such as the profile and amplitude of the laser field envelope, that minimize the variance of the energy distribution.
