ABSTRACT:
In order to remove a dielectric coating from a conducting material, a high energy radiation source, such as a laser source, is focused in a region having a predefined relationship with the coating of the conducting material. The focused radiation results in a plasma or ionized region being formed. The coating in the vicinity of the plasma region is removed. The region of the focusing of the radiation is varied spatially to remove the dielectric coating in a pre-selected region of the conducting material. According to one embodiment, the radiation is focused in a region spatially removed from the conducting material in order that the direct radiation does not directly impact the conducting material.
