Abstract
The free-electron laser simulation code FRED, developed at LLNL primarily to model single-pass free-electron laser (FEL) amplifiers driven by induction linear accelerators, is described. The main emphasis is on the modelling of optical propagation in the laser, and on the differences between the requirements for modelling rf-linac-driven vs. induction-linac-driven FEL's. Examples of optical guiding and mode cleanup are presented for a 50 pm FEL.Keywords
