ABSTRACT:
A decohered laser light production system is provided. The decohered laser light system comprises a laser source. The system further comprises a multi-mode fiber having an input face, an output face and a body for propagating light from the input face to the output face, the input face arranged to accept laser light from the laser source, the body comprising a length such that laser light is generally decohered when exiting the output face.
