Abstract: A laser cutting system, including a steering mirror assembly for directing a laser beam through a predetermined cutting path along a workpiece or substrate material. The steering mirror assembly includes a base, and a mirror pivotally supported on the base by a flexure assembly which confines pivotal movement of the mirror about a vertical Y-axis and/or about a horizontal X-axis. A pair of electrical actuator assemblies include movable bobbin assemblies connected to the mirror by control rod flexures at locations on the mirror which are spaced 90° apart from one another. In operation, selective electrical energization of the actuator assemblies controls movement of the bobbin assemblies to pivot the mirror about the vertical Y-axis and/or about the horizontal X-axis throughout a number of angular orientations to thereby direct the laser beam through a predetermined cutting operation pattern along the substrate surface to cut materials from the substrate.
