Abstract

Free space optical communication systems require high quality laser diode collimators capable of long term operation in the space environment. A four-element collimator with all-spherical surfaces was designed and built using conventional fabrication technologies and specialized assembly techniques. Final assemblies demonstrated 1/50-wave rms wavefront errors and no destabilizing feedback to the laser diode source. Advanced collimator designs employing aspheres reduce the collimator design complexity and cost while maintaining optical performance. Examples of these advanced designs, based on lens molding technologies, demonstrate suitability to space applications.
