Abstract

In this paper attention is given to the effects of primary coma on the linearly polarized Lorentz– Gauss beam with one on-axis optical vortex was investigated by vector diffraction theory. It is observed that by properly choosing the topological charge one can obtain many novel focal patterns suitable for optical tweezers, laser printing and material process. However, it is observed that the focusing objective with coma generates structural modification and positional shift of the generated focal structure.
