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 15):
An optical fiber comprising:\n a first segment comprising:\n a first core portion comprising a first central core region, a first annular core region, and a first low-index core region, wherein the first central core region is disposed within the first annular core region and is spaced apart from the first annular core region by the first low-index core region; and \n a first cladding portion extending around the first core portion, the first central core region having a relative refractive index \u0394 CC  % relative to the first cladding portion, the first annular core region having a relative refractive index \u0394 AC  % relative to the first cladding portion, and the first low-index core region having a relative refractive index \u0394 LIC  % relative to the first cladding portion, wherein \u0394 LIC  % is less than \u0394 CC  % and \u0394 AC  %; \n a second segment comprising:\n a second core portion comprising a second central core region, a second annular core region, and a second low-index core region, wherein the second central core region is disposed within the second annular core region and is spaced apart from the second annular core region by the second low-index core region, wherein at least the second central core region is optically coupled to the first annular core region; and \n a second cladding portion extending around the second core portion, the second central core region having a relative refractive index \u0394 cc  % relative to the second cladding portion, the second annular core region having a relative refractive index \u0394 ac  % relative to the second cladding portion, and the second low-index core region having a relative refractive index \u0394 lic  % relative to the first cladding portion, wherein \u0394 lic  % is less than \u0394 cc  % and \u0394 ac  %.
