  • Patent number: 5173583
    Abstract: A specular system for recovering the energy of a reflected laser beam is disclosed which has a plurality of reflecting surfaces positioned so as to further reflect the reflected laser beam back onto the workpiece surface. The normals of the reflecting surfaces are displaced from the point at which the laser beam impinges upon the workpiece from a laser head. The reflecting surfaces may be plane or curved and focusing such that they take the form of segments of spheres or cylinders, depending upon the particular application of the system. The reflecting surfaces are characterized by different curvatures or by discontinuous orientations. The reflecting surfaces may be formed on a common reflector, or may be individually formed on separate reflectors. In the latter instance, the separate reflectors may be mutually adjustable both with respect to each other and with respect to the laser head.
