Abstract
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.
