1. A method of welding or marking a part with an optical scan system that directs an optical beam onto the part at an energy density level sufficient to weld or mark it, comprising controlling a pattern of the beam on the part by disposing a waveguide between the part and an optical source of the optical scan system to prevent areas of the part that are not to be exposed to the beam at the sufficient energy density level from being exposed to the beam at the sufficient energy density level and to prevent the beam from being reflected in an undesired direction.
