• vortex beams is shown in Figure 10a [151]. The material ablated with such a beam has been shown to form twisted nanostructures on metal surfaces with controlled chirality [151][152]. They are formed due to the involvement of ablated/molten material in a spiral motion of the vector vortex beam as

• . In contrast, ablation with a Gaussian beam results in the ejection of molten droplets from the overheated central region and the formation of a crater rim. For instance, it has been demonstrated that during vortex-beam ultrashort laser ablation of thin metal films [55] and tungsten targets in air [56

• ; Bessel beam; electron-beam shaping; nanofabrication; vortex beam; Introduction The possibility to shape electron beams has gained much interest since the first observation of electron vortex beams, i.e., beams that carry a defined orbital angular momentum [1][2][3]. Various other beam shapes, e.g., non
