Abstract

A method for processing a transparent workpiece that includes directing a laser beam output by a beam source onto a phase-adjustment device such that the laser beam downstream the phase-adjustment device is an Airy beam and directing the Airy beam onto a surface of the transparent workpiece. The Airy beam forms an Airy beam focal region in the transparent workpiece, the Airy beam of the Airy beam focal region having a maximum intensity of 100 TW/cmor less, the Airy beam of the Airy beam focal region induces absorption in the transparent workpiece, the induced absorption producing a curved defect in the transparent workpiece.
