Abstract
We demonstrate experimentally dynamical acoustic and optical “drill” beams, presenting nonstationary intensity distributions that resemble the spinning mechanical drill. The drills appear as the spatiotemporal interference of two Bessel-vortex beams of different topological charges and different carrier frequencies. We explore material processing with such drills.
