Low voltage free electron laser optics: First stage design
Abstract
This study verified the simple conceptual design parameters of the two stage FEL with detailed calculations of electron dynamics. The agreement between the two is quite reasonable. These calculations assume a plane wave propagating through the wiggler. For a given stable cavity configuration, the actual transverse intensity profiles were then calculated using perturbation techniques. The theory used should be accurate for single pass gains less than 50% and for cavity lengths long compared to the wiggler length. In the continuation of this program, the results of the present calculations will be used to determine the performance of the second stage of the free electron laser that will produce output in the visible portion of the electromagnetic spectrum.
