Abstract

The laser-based fabrication of glass substrates with chamfered edges and arbitrary contour geometries is reported. To achieve energy deposition along any edge geometry, a holographic beam splitter is used generating a large number of focus copies in the bulk of transparent materials. If an adapted rotation of the focus distribution is additionally used during machining, the production of substrates with arbitrary contours, such as circular or display geometries, is enabled. After the laser modification step, separation is achieved using a selective laser etching strategy. The advantages of our process are discussed using selected process results and associated laser parameters.
