Abstract
Double-charge femtosecond vortices were synthesized with the polarization-singularity beam converter [1]. The vortex was focused using moderate and high numerical aperture optics (NA = 0.45 and 0.9) to ablate fused silica and soda-lime glasses. The results demonstrate that the ablation can be controlled on a sub-micrometer scale with a high degree of repeatability.
