1. A supercontinuum light source comprising:
a microstructured fiber (MSF) comprising a core extending along a longitudinal axis of the MSF and a cladding region surrounding the core, wherein at least the cladding region comprises a plurality of inclusions extending along the longitudinal axis of the MSF in at least a length section, wherein the MSF, in at least a selected length section of said length section, comprises at least one of hydrogen and deuterium, wherein the MSF, in at least said selected length section, further comprises a coating surrounding the cladding region, wherein the coating is hermetic for said hydrogen and/or deuterium at a temperature below Th, wherein Th is at least about 50° C., and
a pump source arranged to feed pump pulses to a launching end of the MSF, where the pump pulses have a peak power at the launching end of the MSF of at least about 5 kW.
