Abstract

Today many applications of high power lasers for medical purposes are known. In some applications it is advantageous, in others necessary to use laser-beam transmission via light guides. An assembly which transports laser light from the source to a target via a fiber is called a fiber optic beam delivery system or BDS. Most of these systems consist of the following parts (Fig. 1): - laser, - coupling optics, - fiber, and - focussing optics. Some systems contain even more components e.g. in ophtalmology for reflecting the beam into a microscope. Any practical system uses connectors to separate the individual parts. The fiber will be confectionated into a cable with connectors with or without optical systems integrated. Because the systematic development of BDS is only at the beginning, we will give some brief considerations how to achieve an optimized BDS. We will only consider continuous wave multimode laser beams. For a given problem one will have to - define the desired performance, - choose the appropriate components, and finally - adapt these components to each other.
