A supercontinuum source including 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 including 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.

Reducing light-induced loss in optical fibre

A depolarizing homogenizer including one or more lenslet arrays, for providing a plurality of beamlets associated with different respective parts of a received beam. The depolarizing homogenizer includes 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 the plurality of beamlets. A lens is arranged to at least partially overlap the beamlets having the altered polarization characteristics.

Depolarizing homogenizer

A light source assembly having N outputs, the assembly including: a light source arrangement arranged for supplying light to M inputs, where M an N independently of each other are integers and where M&#x2265;2 and M&#x2265;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 include 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.
