Abstract
A method for processing a transparent workpiece including directing a laser beam in a first orientation along a first beam pathway where a first portion of the laser beam includes a first laser beam focal line and generates an induced absorption to produce a first defect segment within the transparent workpiece. The method further includes adjusting the laser beam to a second orientation along a second beam pathway where a second portion of the laser beam includes a second laser beam focal line and generates the induced absorption to produce a second defect segment within the transparent workpiece. Each of the first and second laser beam focal lines include a circular angular spectrum within the transparent workpiece; and at least one of the laser beam focal lines include an internal focal line angle of greater than 10° relative to a plane orthogonal to the impingement surface at the impingement location.
