System for controlled distribution of laser dosage

An apparatus for distributing an output beam from an intense light source in a treatment pattern, comprising:

• a plurality of optical fibers, the fibers having input ends and output ends;
• first means, coupled with the input ends of the plurality of optical fibers, for securing the input ends in a scan configuration for receiving the output beam;
• means, receiving the output beam, for scanning the beam to supply the beam into the input ends of successive subsets of the plurality of optical fibers in the scan configuration, wherein at least one of the successive subsets includes more than one optical fiber;
• and
• second means, coupled with the output ends of the plurality of optical fibers, for securing the output ends in a treatment configuration for distributing the output beam in a treatment pattern;
• wherein the output end of a member of the at least one subset including more than one optical fiber is non-adjacent to the output end of any other member of the at least one subset.
