Abstract:
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.

Claim (Index 47):
A step-clad optical fiber for use in a laser system comprising (i) a beam source for emission of an input laser beam and (ii) an in-coupling mechanism for receiving the input laser beam and directing the input laser beam toward an input end of the step-clad optical fiber for emission as an output beam from an output end of the step-clad optical fiber opposite the input end, the step-clad optical fiber comprising:\n a central core having a first refractive index; surrounding the central core, a first cladding having a second refractive index; surrounding the first cladding, an annular core having a third refractive index; and surrounding the annular core, a second cladding having a fourth refractive index, wherein (i) the first refractive index is larger than the fourth refractive index, (ii) the third refractive index is larger than the fourth refractive index, (iii) the second refractive index is smaller than the first refractive index and larger than the fourth refractive index, and (iv) the third refractive index is larger than the first refractive index.
