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 11):
The optical fiber of  claim 1 , wherein:\n the first core portion further comprises a first low-index core region having a relative refractive index \u0394 LIC  % relative to the first cladding portion, wherein the first low-index core region is disposed within the first annular core region and \u0394 AC  % is greater than \u0394 LIC  %; and the second core portion of the second segment comprises:\n a second annular core region centered on the axial centerline of the optical fiber and having an inner radius r 0  and a radial thickness t ac =r 1 \u2212r 0 , the second annular core region having a relative refractive index \u0394 ac  % relative to the second cladding portion, wherein \u0394 ac  % is equal to \u0394 c  %; and \n a second low-index core region having a relative refractive index \u0394 lic  % relative to the second cladding portion, wherein the second low-index core region is disposed within the second annular core region and \u0394 ac  % is greater than \u0394 lic  % and \u0394 AC  % is substantially equal to \u0394 ac  %.
