LASER FORMING NON-SQUARE EDGES IN TRANSPARENT WORKPIECES USING MODIFIED AIRY BEAMS

Abstract:

A method includes directing a laser beam onto a phase-adjustment device such that the laser beam downstream the phase-adjustment device is a modified Airy beam having a modified Airy beam focal region having a main lobe and a plurality of side lobes. The main lobe has a lobe aspect ratio of 1.2 or greater.
