    "abstract": "The collective and single-electron amplification regimes of a non-collinear\nfree electron laser are analyzed within the framework of dispersion equations.\nThe small-signal gain and the conditions for self-amplified excitations are\nfound. The collective excitations in a free electron laser are shown to be\nfavored by the non-collinear arrangement of the relativistic electrons and the\nlaser wave. Implications for free-electron lasing without inversion are\ndiscussed.",
