Dynamics of asymmetrical topological multiples in combined singular beams
It is represented the theoretical results confirming the existence of the optical vortices after a low mode fiber end, while there are no free optical vortices propagating along the fiber itself.
Particle trapping and transportation by high-intensity singular beams
The combined singular beams generated by saddle-like imperfections of the cover glass surface in IR spectral range is subjected to the unfolding process near the focal plane of a microobjective. As fa...

Thehigh-intensity singular beam turns out to be created by meansof the ordinary cover glass for a microscope. For thisit is necessary to place the edge of the coverglass into the high-power fundamental laser beam. At the expenseof the technical wedging of the cover glass beyond thetransparent appears the high-quality singular beam bearing the optical vortex.The given paper represents the physical mechanism of such processillustrated with the vast experimental and theoretical results.
