Abstract

We analyze the concept of using customized spatially variable waveplates for beam tailoring towards enhanced various glass microwelding process. These elements work as precise flat optical elements that have very high diffraction efficiency (<90%), high optical damage threshold, and can be freely customized for specific needs that transform the spatial intensity profile into tailored beam shape. In this work, we investigate custom made flat-top beam and "C" shaped beams for deep microwelding purposes. By using numerical simulations and experimental research we compare the performance of such beams and demonstrate thin glass deep microwelding capabilities using custom beam shaping elements.
