    "abstract": "We present a study of the interaction of a relativistically planar channeled\nelectron with an intense electromagnetic field. Using a S-Matrix approach in\nthe Strong Field Approximation, it is shown that the crystal periodicity\naffects drastically the excitation process, suppressing the possibility of\nmultiphoton absorption except for some particular cases. This selective\nexcitation opens the possibility to control the dynamics of the channeling\nprocess by means of an external field. Explicit expressions for the S-matrix\nN-photon excitation rates together with the corresponding conservation laws are\nobtained from the relativistic quantum mechanical Dirac equation.",
