英文摘要	An optical beam delivery device. The device comprises a first length of fiber comprising a first RIP formed to enable the adjusting of one or more beam characteristics of an optical beam by a perturbation device. The optical beam delivery device further comprises a second length of fiber having a proximal end for receiving the optical beam from the first length of fiber and a distal end. The proximal end is coupled to the first length of fiber. The second length of fiber comprises a second RIP formed to confine at least a portion of the optical beam within one or more confinement regions. A beam modification structure is disposed at, or a distance from, the distal end of the second length of fiber. The beam modification structure is configured to modify at least one property of the optical beam chosen from beam divergence properties, beam spatial properties and beam directional characteristics.
