Abstract
Disclosed herein are methods, apparatus, and systems for providing an optical beam delivery device, comprising a first length of fiber comprising a first RIP formed to enable modification of one or more beam characteristics of an 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 the modified beam characteristics of the optical beam within one or more confinement regions.
Claims25
An optical beam delivery device, comprising:
- a first length of fiber comprising a first refractive index profile (RIP) formed to enable modification of two or more beam characteristics of a guided 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 the modified beam characteristics received from the first length of fiber within two or more confinement regions, wherein the first RIP and the second RIP are different and the first length of fiber and the second length of fiber form at least a portion of a continuous fiber length.
The optical beam delivery device of 1, wherein the second length of fiber comprises a central core having a diameter in a range of about 0 to 100 microns, a first annual core encompassing the central core having a diameter in a range of about 10 to 600 microns and a second annular core having a diameter in a range of about 20 to 1200 microns.
An optical beam delivery device, comprising:
- a first length of fiber comprising a first refractive index profile (RIP) formed to enable modification of two or more beam characteristics of an optical beam by a perturbation device;
- and
- a second length of fiber having a second RIP defining at least two confinement regions and coupled to the first length of fiber, the second RIP formed to confine at least a portion of the modified beam characteristics of the optical beam within the at least two confinement regions.
