Abstract

In this paper, we theoretically and numerically consider the sharp focusing of a laser beam whose polarization pattern in the initial plane is a superposition of a cylindrical vector beam of order m and a homogeneous linear polarization. At the focal spot of such a beam, for odd m, there will be areas with elliptical or circular polarization with alternating directions of rotation. For even m at the focal spot, the field is linearly polarized at every point and has no transverse energy flux. These beams can be used to create a micromachine in which two microparticles in the form of gears are captured in the focal spot of the beam into neighboring local areas in which the energy flux twists in various directions, and therefore, these gears will also twist in various directions.
