The paper studies a simulation of a one-dimensional nonlinear free electron laser that
includes a square hybrid wiggler, prebunched electron beam, and ion-channel guiding …

Spontaneous emission of free electron laser with planar wiggler and ion-channel guiding is
calculated analytically and possibility of emission at up-shifted wiggler or ion-channel …

In this paper, amplification and saturation properties of one dimensional free electron laser
(FEL) operating in Raman regime with helical wiggler and axial magnetic field are studied …

The effect of axial energy spread on the radiation of third harmonic is studied in the free
electron laser with planar wiggler and ion-channel guiding. Spread in the longitudinal …

Increasing the output power of a long-wavelength free-electron laser (FEL), despite the
destroying effects of beam energy spread, is studied using the optimal pre-bunching of the …
