Protecting the edge: Ultrafast laser modified C-shaped glass edges

Daniel Flamm et al.

Summary: A procedure and optical concept are introduced for cleaving transparent materials with customized edges using ultrashort pulsed lasers in a single pass. The procedure involves holographically splitting foci along the desired edge geometry, including C-shaped edges with local 45-degree tangential angles. Single-pass, full-thickness laser modifications are achieved with single-side access to the workpiece, and actual separation is performed using selective etching strategy after inducing laser modifications at a feed rate of approximately 1 m/s.

Transversal and axial modulation of axicon-generated Bessel beams using amplitude and phase masks for glass processing applications

Juozas Dudutis et al.

Summary: This study investigates the effects of different masks on Bessel beams and demonstrates the control of laser-induced microcracks in transparent materials by selecting the appropriate intensity level and introducing additional amplitude modulation.
