  • Fiber optic laser beam delivery system
    Patent number: 4944567
    Abstract: The invention relates to a laser light beam delivery system for delivering a laser light beam from a source remote from the laser originating the light. The delivery system consists of an optical fiber having a double taper, i.e., a taper portion at each end with the fiber tapering at the input end and at the output end to a diameter substantially greater than the actual diameter of the fiber. This permits high power transmission capabilities in as much as the greater diameter portions distribute the average energy such that no damage to the fiber is presented.
