Abstract:
An optical fiber for converting a Gaussian laser beam into a Bessel laser beam may include a first segment optically coupled to a second segment with a transition region, the first segment having a first outer diameter greater than a second outer diameter of the second segment. The first segment may include a first core portion with a first cladding portion extending around the first core portion. The first core portion may have an annular core region with a relative refractive index relative to the first cladding portion. The second segment may include a second core portion with a second cladding portion extending around the second core portion. The second core portion has a relative refractive index relative to the second cladding portion and the relative refractive index of the first annular core region may be substantially equal to the relative refractive index of the second core portion.

Claim (Index 1):
An optical fiber comprising:\n a first segment comprising:\n a first core portion having a radius R 1  from an axial centerline of the optical fiber, the first core portion comprising a first annular core region centered on the axial centerline of the optical fiber and having an inner radius R 0  and a first radial thickness T AC =R 1 \u2212R 0 ; and \n a first cladding portion extending around the first core portion, the first cladding portion having a radial thickness T CL , the first annular core region having a relative refractive index \u0394 AC  % relative to the first cladding portion; \n a second segment comprising:\n a second core portion having a radius r 1  from the axial centerline of the optical fiber, wherein at least a portion of the second core portion is optically coupled to the first annular core region and the radius R 1  is greater than the radius r 1 ; and \n a second cladding portion extending around the second core portion, the second cladding portion having a radial thickness t cl  that is less than the radial thickness T CL  of the first cladding portion, the second core portion having a relative refractive index \u0394 c  % relative to the second cladding portion, wherein \u0394 AC  % is substantially equal to \u0394 c  %.
