    摘要： 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.

    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.

    摘要： An optical beam delivery system, includes: an optical beam source; a fiber assembly situated to receive and modify one or more beam characteristics of an optical beam; and a nonlinear frequency-conversion stage in optical communication with the fiber assembly and situated to receive and frequency-convert an optical beam from a first wavelength to one or more second wavelengths. The fiber assembly includes: a first length of fiber comprising a first RIP formed to enable modification of the one or more beam characteristics of the optical beam by a perturbation device, and a second length of fiber having a second RIP coupled to the first length of fiber, the second RIP formed to confine at least a portion of modified beam characteristics of the optical beam within one or more confinement regions. The first RIP and the second RIP are different.
