Analyses on the low voltage free electron laser
Abstract
The results of calculations on the two stage free electron laser (FEL) are presented. Methods to reduce mirror losses at mm wavelengths are suggested. Dielectric stack with teflon and air seem to be the optimum choice to reduce absorption loss. Several methods to maintain a single longitudinal mode operation of the first stage of a two stage FEL are suggested. Finally, the design issues concerned with applying axial electric field by induction to enhance FEL extraction efficiency are discussed.
