            Abstract : 
A nonlinear model of a grating free-electron laser is formulated that includes the effects of self-field forces, beam emittance, energy spread and gyromotion in a guide field. We compare the efficiency of an infinitely-thin beam, a finite-thickness beam with laminar flow and a finite-thickness beam with full transverse motion. For a thick beam, the effect of electron gyration about the beam axis is to enhance the efficiency as compared to that for a beam with laminar flow.
