<p>A system and method for forming micro- and meso-scale features in ductile and brittle surfaces. One or more laser pulses are applied to an ablative coating on a workpiece. The laser pulses cause the coating to ablate and plasma to be created in a space between a confining medium and the workpiece. The creation of plasma within the confined space generates a shockwave that deforms the workpiece, ultimately shaping the workpiece to an underlying mold. The number of laser pulses that are applied to shape a workpiece depends on the composition and thickness of the workpiece, type of laser, composition and thickness of ablative and confining material, and amount of desired deformation. For some materials, the workpiece may be preheated before being deformed.</p> |
