摘要	In various embodiments, the beam parameter product and/or beam shape of a laser beam is adjusted by coupling the laser beam into an optical fiber of a fiber bundle and directing the laser beam onto one or more in-coupling locations on the input end of the optical fiber. The beam emitted at the output end of the optical fiber may be utilized to process a workpiece.
其他摘要	在各种实施例中，激光束的光束参数乘积和/或光束形状通过将激光束耦合到光纤束的光纤中并且将激光束引导到光纤束的输入端上的一个或多个输入耦合位置光纤。在光纤的输出端发射的光束可用于处理工件。
主权项	A laser system having multiple outputs, the system comprising: a beam emitter for emission of a laser beam; a fiber bundle comprising a plurality of optical fibers, each of the optical fibers having (i) an input end for receiving a laser beam, and (ii) opposite the input end, an output end for delivery of the received laser beam to a workpiece; a reflector for receiving the laser beam and reflecting the laser beam toward the fiber bundle; an optical element for receiving the laser beam from the reflector and coupling the laser beam into only one of the input ends of an optical fiber in the fiber bundle; and a controller for causing and controlling relative motion between the input ends of the optical fibers and at least one of the reflector or the optical element to thereby determine at least one of (i) the optical fiber of the fiber bundle into which the laser beam is coupled or (ii) a location at which the laser beam is directed on an end face of a selected fiber, whereby at least one of a beam shape or a beam parameter product is determined at least in part by the coupling of the laser beam into the optical fiber.
