Abstract
A laser machining device is capable of simultaneously machining two- or three dimentional patterns on the surface of a workpiece. A micromirror array positioned within a laser cavity generates a patterned plurality of laser beamlets which can be homogenized and deflected by a second micromirror array onto the surface of a workpiece to create a two-dimensional pattern. Alternatively, the second micromirror array can deflect laser beamlets of unequal energy density to produce a three-dimensional pattern.
