Abstract

The fast-growing market for consumer-devices based on Augmented Reality (AR) technology requires optical waveguides. These components, which are used for image projection, are made of high-index glass or other transparent materials. Cutting eyeglasses out of the bare or preprocessed material has complex requirements for today’s available processes. For some years now, laser-cutting processes of transparent materials with ultrashort pulse (USP) lasers have been increasingly adopted in those industrial applications. The ability of a fully automated process flow is of critical importance, especially for AR products, which target the mass production market. Laser cutting tools combine good edge quality with fully automated process flows and free-form capability. This presentation covers the advantages of laser technology based on application examples for AR waveguides
