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 20):
The optical system of  claim 17 , the first segment further comprising\n a first cladding portion extending around the first core portion; the first core portion comprising a first central core region disposed within the first annular core region, the first annular core region spaced apart from the first central core region by a first low-index core region, wherein the first central core region has a relative refractive index \u0394 CC  % relative to the first cladding portion, the first annular core region has a relative refractive index \u0394 AC  % relative to the first cladding portion, and the first low-index core region has a relative refractive index \u0394 LIC  % relative to the first cladding portion, wherein \u0394 AC  % is greater than or substantially equal to the \u0394 CC  % and \u0394 CC  % is greater than \u0394 LIT  %; the second segment further comprising: a second cladding portion extending around the second core portion, the second core portion comprising a second central core region disposed within a second annular core region, the second annular core region spaced apart from the second central core region by a second low-index core region, wherein the second central core region has a relative refractive index \u0394 cc  % relative to the second cladding portion, the second annular core region has a relative refractive index \u0394 ac  % relative to the second cladding portion, and the second low-index core region has a relative refractive index \u0394 lic  % relative to the second cladding portion, wherein \u0394 ac  % is greater than or substantially equal to \u0394 cc  % and \u0394 cc  % is greater than \u0394 lic  %.
