  • Patent number: 10775575
    Abstract: A water-cooled package of a fiber-optic transport head comprising a delivery optical fiber (DOF), an interface optics, an end plug, an optically transparent tube, a tube holder comprising multiple broken cuts, and a housing operates for delivering a high-power laser light from DOF to free space. The interface optics is fusion-spiced with a section of DOF with a cladding exposed whereas the section of DOF with the cladding exposed is enclosed in a bore of the optically transparent tube, working together as a cladding mode stripper. The multiple broken cuts allow optical energy from the cladding mode stripper to randomly launch the housing in a way that the optical energy is uniformly distributed, thereby no localized hot spots possibly existed. The housing comprises a set of internal threads comprising a helix angle and a tooth height. The set of internal threads facilitates thermal dispersion, effectively reducing temperature on the housing.
