Abstract
The embodiments disclosed herein relate to methods, systems, and system components for creating and arranging small (micron and smaller) defects or perforations in transparent materials in a particular manner, and, more particularly, to the arrangement of these defects, each of which has an average crack length, in a predetermined spaced-apart relation (each defect separated from an adjacent defect by a predetermined distance) defining a contour in a transparent material to lower the relative interface fracture toughness for subsequent planned induced separation.
