1. A supercontinuum light source comprising a microstructured optical fiber, and a feeding unit arranged for feeding pump pulses to said microstructured optical fiber,
wherein said feeding unit comprises a picosecond laser and one or more amplifiers,
wherein said microstructured optical fiber is a silica fiber having a core comprising a core material,
wherein at least a part of the core being of silica or doped silica, and
said microstructured optical fiber further comprising a cladding surrounding the core, and
at least said core material is loaded with deuterium to have an OD absorption peak around 1870 nm,
wherein said feeding unit is spliced to said microstructured optical fiber [ ,
wherein said OD absorption peak corresponds to a deuterium loading of said deuterium loaded material of 0.1 atom percent (at percent) bound deuterium or more] .
