Abstract

We combine conventional beam shaping with simultaneous spatial and temporal focusing (SSTF) to generate femtosecond SSTF vortex beams. We demonstrate the utility of these beam structures by producing single-shot encryption of doughnut-shaped ablation marks on the back surfaces of glass plates. The SSTF enables this type of machining by significantly reducing the nonlinear beam distortions on propagation through the glass.
