Abstract :
In this work the movement of the microscopic absorbing particles along the fixed trace formed by the beams with predetermined intensity and orbital momentum distributions was demonstrated for the first time. The rotation was obtained for the particles of the size more than the beam diameter. The beams were formed with special diffraction optical elements.
