Abstract: 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.

Abstract: A method of processing by controlling one or more beam characteristics of an optical beam may include: launching the optical beam into a first length of fiber having a first refractive-index profile (RIP); coupling the optical beam from the first length of fiber into a second length of fiber having a second RIP and one or more confinement regions; modifying the one or more beam characteristics of the optical beam in the first length of fiber, in the second length of fiber, or in the first and second lengths of fiber; confining the modified one or more beam characteristics of the optical beam within the one or more confinement regions of the second length of fiber; and/or generating an output beam, having the modified one or more beam characteristics of the optical beam, from the second length of fiber. The first RIP may differ from the second RIP.

Abstract: A method of tailoring beam characteristics of a laser beam during fabrication of an electronic device. The method includes: providing a substrate comprising one or more layers; adjusting one or more characteristics of a laser beam; and impinging the laser beam having the adjusted beam characteristics on the substrate to carry out at least one process step for fabricating the electronic device. The adjusting of the laser beam comprises: perturbing the laser beam propagating within a first length of fiber to adjust the one or more beam characteristics of the laser beam in the first length of fiber or a second length of fiber or a combination thereof, the second length of fiber having two or more confinement regions; coupling the perturbed laser beam into the second length of fiber; and emitting the laser beam having the adjusted beam characteristics from the second length of fiber.
