A free electron laser (FEL) operation in the far infrared or millimeter wave region of the spectrum requires the use of a waveguide to confine the radiation. A new tapering scheme for the operation in the high gain regime, in the amplifier configuration, can thus be utilized in which the waveguide gap is varied while the undulator magnetic field and period are kept constant. The results of a numerical code are presented. © 1993.
