Abstract
Official abstract text for this publication.
In various embodiments, the beam parameter product and/or numerical aperture of a laser beam is adjusted utilizing a step-clad optical fiber having a central core, a first cladding, an annular core, and a second cladding.
First claim
Opening claim text (preview).
What is claimed is: 1. A step-clad optical fiber having an input end and an output end opposite the input end, the step-clad optical fiber comprising: a central core having a first refractive index that is constant across an entire diameter of the central core, wherein the central core is composed of fused silica or fused silica doped with fluorine, titanium, germanium, and/or boron; surrounding the central core, a first cladding having a second refractive index; surrounding t…
