Abstract
A cladding stripper includes a plurality of transversal notches or grooves in the outer surface of an exposed inner cladding of a double clad optical fiber. Position and orientation of the notches can be selected to even out cladding light release along the cladding light stripper, enabling more even temperature distributions due to released cladding light. The notches on the optical fiber can be made with a laser ablation system.
Claims20
A cladding light stripper comprising:
- a double-clad optical fiber having a core for guiding signal light, an inner cladding surrounding the core, and an outer cladding surrounding the inner cladding,
- wherein the optical fiber includes a stripped portion wherein the outer cladding is removed, forming an exposed section of an outer surface of the inner cladding, wherein the exposed section includes a plurality of transversal notches disposed along the fiber, to enable light to escape the inner cladding upon impinging on the notches, wherein each of the plurality of notches has a depth of only a partial distance to the fiber core.
