Abstract: A light source assembly having N outputs is disclosed. The assembly comprising: • a light source arrangement arranged for supplying light to M inputs, where M an N independently of each other are integers and where M ≥ 2 and M ≤ N; • at least one optical couplers, each having at least one input arm and a plurality of output arms; and • an integer number, P, of mode scramblers; The light source arrangement may comprise a broadband light source and a multimode coupler configured for receiving one or more light beams from the light source arrangement, wherein the one or more light beams being derived from the broadband light source and wherein a mode scrambler is arranged for mode scrambling one of said light beams before it enters the multimode coupler.

Abstract: A supercontinuum source, comprises a pump source and a supercontinuum generator configured for receiving electromagnetic radiation derived from the pump source and for generating supercontinuum radiation, the supercontinuum generator comprising a nonlinear microstructured optical fibre having a core region comprising silica. The core region includes a dopant selected to reduce light-induced non-bridging oxygen hole centre loss in the nonlinear microstructured optical fibre.

Abstract: A depolarizing homogenizer comprises one or more lens let arrays, for providing a plurality of beamlets associated with different respective parts of a received beam. The depolarizing homogenizer comprises a depolarizer comprising different areas which affect polarization differently, the depolarizer being positioned to cause alteration of the polarization characteristics of at least some of said plurality of beamlets. A lens is arranged to at least partially overlap the said beamlets having said altered polarization characteristics.
