ABSTRACT:
A mechanism for distributing the output beam from a laser system in a treatment pattern that comprises a plurality of optical fibers, having input ends and output ends. At the input ends, the fibers are secured in a scan configuration for receiving an output beam from a laser. At the output ends, the fibers are configured in a treatment configuration for distributing the output beam in a treatment pattern. A scanner coupled with the laser system directs the beam in a scan pattern at the input ends of the fibers which matches the scan configuration. The treatment configuration secures the output ends of the optical fibers so that the output end of one optical fiber sequentially receiving the beam from the scanner is non-adjacent the output end of a next optical fiber sequentially receiving the beam from the scanner.
