WebOptical vortices are studied by creating them in the lab in various ways. They can be generated directly in a laser,[2][3]or a laserbeam can be twisted into vortex using any of … Webexhibits a phase singularity on the beam axis and there-fore vanishes at this point due to destructive interference. Acoustic vortex beams can transfer their angular momen-tum to microscopic and macroscopic solid objects [7–12] and to fluids [13] and exert mechanical torques on them. In addition, the singular scattering of vortex beams by
