摘要： A source of optical supercontinuum radiation comprises a length of microstructured optical fibre and a pump laser adapted to generate lasing radiation at a pump wavelength. The length of microstructured optical fibre is arranged to receive lasing radiation at the pump wavelength to generate optical supercontinuum radiation and comprises a core region and a cladding region which surrounds the core region. The source of optical supercontinuum radiation is arranged such that at a location along the length of the microstructured optical fibre (a) the microstructured optical fibre comprises a group index (GI) versus wavelength curve having a zero crossing wavelength (ZCW) at which the group velocity dispersion has a zero crossing and such that the GI increases for wavelengths away from the ZCW such that the curve includes group indices that are greater than the GI at the ZCW for wavelengths greater than as well as less than the ZCW; (b) light having a wavelength of greater than 2000 nm propagates along the length of microstructured optical fibre and has a GI that is matched to the GI of light that propagates along the length of microstructured optical fibre and that has a wavelength of less than 400 nm; and (c) the pump wavelength is within 200 nm of the ZCW.
