Abstract

In this paper we describe the results of a polarization-based Strehl ratio analysis for a high energy laser system which includes a large diameter Cassegrain beam expander and a four fold mirror coude telescope. The analysis takes into account coating characteristics and telescope pointing direction changes. Multilayer dielectric coatings on curved optical surfaces in a high-energy laser system will affect far-field system performance due to variations in phase retardance and reflectance across the aperture. Since control of the coating process becomes more difficult as the size of the coated optic increases, systemic coating thickness variations will introduce additional aberrations.
