Paper Abstract

A static computer-aided method used to align a visible wavelength grazing incidence ring resonator for a free-electron laser (FEL) is presented with a brief description of the hardware, results of numerical simulations, and actual initial data. A computer-aided alignment scheme is particularly useful for this application due to the optical system complexity and the need for precise results. Although the system hardware has not yet been perfected, initial data shows that this technique works and presents a viable solution to this alignment problem. Utilizing information from an interferogram taken at a single axial field point and information about the chief ray of the optical system, it is shown that it is possible to converge to an alignment solution using a constrained damped least squares optimization in a commercially available lens design package.
