Abstract
A supercontinuum source including a pump source and a supercontinuum generator configured for receiving electromagnetic radiation derived from the pump source and for generating supercontinuum radiation, the supercontinuum generator including a nonlinear microstructured optical fibre having a core region comprising silica. The core region includes a dopant selected to reduce light-induced non-bridging oxygen hole centre loss in the nonlinear microstructured optical fibre.
Claims26
A supercontinuum source, comprising:
- a pump source;
- and
- a supercontinuum generator configured for receiving electromagnetic radiation derived from the pump source and for generating supercontinuum radiation, the supercontinuum generator comprising a passive silica-based microstructured optical fiber having a core region and a cladding region including longitudinally extending air-holes disposed about the cladding region,
- wherein at least a doped region of the core region is doped with boron, wherein the boron reduces light-induced non-bridging oxygen hole center loss in the microstructured optical fiber, and
- wherein the core region of the microstructured optical fiber further comprises hydrogen and/or deuterium.
