Abstract
The present invention is a method and apparatus for producing a hole in a structure utilizing both an unmodulated beam and a modulated beam. The unmodulated beam first breaks through the structure, thereby forming a guide hole, and the modulated beam then produces a reaming effect by increasing the cross section of the hole to the size of the effective diameter of the modulated beam. The modulated beam increases the cross section of the hole because the modulated beam has a higher beam intensity than the unmodulated beam for a given beam radius.
