Abstract

Complex touch panel displays development is requiring high performance glass cutting techniques. Femtosecond lasers, combined to Bessel beam generation based on reflective axicons already showed quality and efficiency improvements, while being able to handle high peak and average power. We described here recent developments for high quality Bessel beam generation using a fully reflective system. This complex Bessel beam presents an intensity plateau along its propagation axis, being twice more homogeneous and having a five times sharper tail compared to a classical Bessel beam. This development paves the way to complex and selective multi-layer glass cutting.
