Abstract
A method of separating a portion of an object comprising: presenting an object having a thickness; using a laser emission at a wavelength to perforate at least a portion of the thickness of the object sequentially over a length to form a series of perforations between a first portion of the object on one side of the series of perforations and a second portion of the object on the other side of the series of perforations; and applying a stress to the object at the series of perforations to separate the first portion of the object from the second portion of the object, wherein the thickness of the object, at the series of perforations, is transparent to the wavelength of the laser emission.
