The interaction between noncollinear laser and relativistic electron beams in static magnetic undulator has been studied within the framework of dispersion equations. In the limit of small-signal gain the spatial growth rates are found for the collective (Raman) and single-electron (Thompson) regimes. For a free-electron laser without inversion (FELWI), estimates of the threshold laser power are found. The large-amplification regime should be used to bring an FELWI above the threshold laser power.
