| 摘要 |
The present invention relates to a super continuum light source comprising a pump source arranged to emit light having a center wavelengthλcenter arranged to provide pump pulse to a generator fibre, where the refractive index profile of the core is arranged to allow modal cleaning of the light is it propagates, such as via stimulated Raman scattering. An example of invention is the application of a relatively high power pump laser utilized to provide an optical super continuum with relatively high spectral density and/or good beam quality even though the pump laser may provide a beam with a high M2.
