    "abstract": "The dynamical response of a relativistic bunch of electrons injected in a\nplanar magnetic undulator and interacting with a counterpropagating\nelectromagnetic wave is studied. We demonstrate a resonance condition for which\nthe free electron laser (FEL) dynamics is strongly influenced by the presence\nof the external field. It opens up the possibility of control of short\nwavelength FEL emission characteristics by changing the parameters of the\nmicrowave field without requiring change in the undulator\u0027s geometry or\nconfiguration. Numerical examples, assuming realistic parameter values\nanalogous to those of the TTF-FEL, currently under development at DESY, are\ngiven for possible control of the amplitude or the polarization of the emitted\nradiation.",
