Abstract

The authors present a technique for modulation laser beams into beams with special properties, capable of trapping and rotating objects of micro-size. There are two approaches covered: the first one utilizes zero-order Bessel beams superposition for light tubes shaping, and the second one forms Bessel beams superpositions with diffractional optical elements with spatially partitioned topological charge or, alternatively, with vortex axicones. The authors also cover micro-mechanical object manufacturing, optimized for rotating in vortex Bessel beams superposition. Results of numerical simulations and experimental data are presented and then discussed.
