  • Patent number: 7590317
    Abstract: The methods and apparatus of the present invention provide advantages for remote laser delivery systems that conduct high levels of light energy through a fiber optic cable to a target surface. Helical fiber optic mode scramblers in accordance with the present invention are an integral portion of a fiber optic cable having a spiral curvature predetermined to advantageously influence the intermodal dispersion characteristics of the fiber optic cable. Various embodiments of helical fiber optic mode scramblers in accordance with the present invention enable delivery of light energy at rates that can exceed continuous deliver of 30 Joules per millimeter squared of cross sectional area of a fiber optics cable. Particular embodiments of a fiber optic mode scrambler in accordance with the present invention include a support structure and a cylindrical sleeve that provide limited longitudinal flexibility maximizing the range of positions in which the fiber optics cable can be dynamically arranged.

  • Publication number: 20060222305
    Abstract: The methods and apparatus of the present invention provide advantages for remote laser delivery systems that conduct high levels of light energy through a fiber optic cable to a selectable target surface. Helical fiber optic mode scramblers in accordance with the present invention are an integral portion of a fiber optic cable having a rigid curvature predetermined to advantageously influence the intermodal dispersion characteristics of the fiber optic cable. The various aspects of the present inventions may be employed to increase the useful life of a fiber optic cable, increase the energy throughput of a fiber optics cable, implement smaller sized scramblers, implement more efficient scramblers or to provide for robust implementations that are also easy to assemble. Scrambler assemblies in accordance with the present invention include a support structure and a cylindrical sleeve that work in tandem to maintain to the predetermined spiral curvature of the helical mode scrambler.
