Abstract
A supercontinuum light source includes a microstructured optical fiber, and a feeding unit arranged for feeding pump pulses to the microstructured optical fiber, wherein the feeding unit comprises a picosecond laser and one or more amplifiers, wherein the microstructured optical fiber is a silica fiber wherein at least a part of the core being of silica or doped silica, and including a core including core material and a cladding surrounding the core, and at least the core material is loaded with deuterium to have an OD absorption peak around 1870 nm, wherein the feeding unit is spliced to the microstructured optical fiber.
Claims26
