摘要	A method of materials processing using an optical beam includes: 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; modifying 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; 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 can be the same as or differ from the second RIP. The modifying of the one or more beam characteristics can include changing the one or more beam characteristics from a first state to a second state. The first state can differ from the second state.
其他摘要	一种使用光束的材料处理方法，包括：将光束发射到具有第一折射率分布（RIP）的第一长度的光纤中;将来自第一长度光纤的光束耦合到具有第二RIP的第二长度光纤中;在第一长度的光纤中，在第二长度的光纤中，或在第一和第二长度的光纤中，修改光束的一个或多个光束特性;和/或从第二长度的光纤产生具有修改的光束的一个或多个光束特性的输出光束。第一个RIP可以与第二个RIP相同或不同。一个或多个光束特性的修改可以包括将一个或多个光束特性从第一状态改变到第二状态。第一个州可以与第二个州不同。
主权项	A method of materials processing using an optical beam, the method comprising: 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 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; and generating an output beam, having the modified one or more beam characteristics of the optical beam, from the second length of fiber; wherein the first RIP differs from the second RIP, wherein the modifying of the one or more beam characteristics comprises changing the one or more beam characteristics from a first state to a second state, and wherein the first state differs from the second state.
