Paper Abstract

The Beacon is a powerful non-coherent CW infra-red laser source which is developed under the Semi-conductor Inter-satellite Link Experiment (SILEX). It will provide a high divergence beam used during the first tracking acquisition sequence of the Spot 4/Artemis optical communication link. The Beacon uses high efficiency anamorphic couplers to deliver output from 19 laser diodes into a single multi-mode Mixing Fiber, the exit of which is integrated at the focal plane of a collimator. Beacon output is maintained at the required level during unit life using an Optical Monitoring System and a Beacon output Tele-Command. The Engineering Qualification Model is now complete and overall performance with respect to the SILEX requirements is presented.
