Trapping and transportation of large microparticles with singular IR beams

The aim of the given paper is to study experimentally the process of the particle trapping and transportation by means of the singular beams in the IR spectral range. As a rule, the micro particles trapping and transportation are usually accomplished by low-intensity laser beams. The fact is that the main instrument of this process is an axial optical vortex. But at present such a singular beams are created at the expense of computer-generated holograms. It is revealed that this technique enables us to generate singular beams in the IR spectral range at least 30 W in light power with the energetic efficiency near 100%
