Various applications such as electron microscopy or the free-electron laser require electron beams with a narrow velocity distribution. In order to control its width, we suggest to use the scattering of the electrons off two counter-propagating light waves generating a one-dimensional ponderomotive potential.
Within non-relativistic classical mechanics, we find that it is indeed impossible to decrease the width of a homogeneous distribution of the initial positions. In contrast, it is possible to compress the velocity distribution for an electron beam with a modulated initial distribution.
