Abstract: A fiber laser system includes a fiber laser connector having a housing to terminate a fiber that generates a laser beam. A chamber extends internally along a length of the housing. A light trap includes a plurality of threads formed along a wall of the chamber to trap light reflected back to the fiber laser connector in response to an application of the laser beam to a workpiece.

Abstract: Methods, systems and an apparatus relating to a heat spreader to be coupled to a heat source having a heat source coefficient of thermal expansion (HS CTE), the heat spreader comprising an anisotropic material having a high expansion axis. The heat spreader also including a surface to be coupled to the heat source, wherein the high expansion axis of the anisotropic material is oblique to the surface of the heat spreader and wherein the high expansion axis of the anisotropic material is oriented at a first angle of rotation about a first axis of the heat spreader wherein the first angle of rotation is selected to optimize a match of a first CTE of the heat spreader with the HS CTE.
