Abstract

The aberrations have been measured for the finished mirrors that are part of the Burst Mode ring resonator of the Free Electron Laser (FEL) being constructed at the Boeing Aerospace Company in Seattle, Washington. This paper presents analysis of these measurements using the GLAD code, a diffraction ray-tracing code. The diffraction losses within the resonator due to the aberrations are presented. The analysis was conducted in two different modes, a paraxial approximation and a full 3-D calculation, and good agreement between the two approaches is shown. Finally, a proposed solution to the problems caused by the aberrations is presented and analyzed.
