Abstract

Simultaneous coupling of the beam from one laser source into many optical fibers or fiber bundles is of interest for many applications. We developed a coupling scheme based on lens arrays to reduce transmission losses. The laser beam is splitted into focused partial beams. Positioning of an optical fiber near each focus allows multiple fiber coupling with similar efficiency as obtained for a single fiber. A prototype designed for coupling of excimer laser radiation into fiber bundles is presented.
