Paper Abstract

An overview of prismatic anamorphic beam expander (ABE) design requirements for free space laser diode communications is presented. Methods of achieving both fixed and variable magnification devices are described, and design characteristics are compared. The design methods are shown to be valid for the particular requirements of optical intersatellite links. Both fixed and variable magnification designs are demonstrated to be capable of meeting the primary optical requirements. For fixed magnifications, the preferred solution in terms of CAD, reflection losses, and material tolerances has a beam deviation of 6.1 deg, usually considered unacceptable because system layout has already been fixed.
