Abstract :
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%
