Paper Abstract

We demonstrate a technique for generation of hollow optical beams (HOB’s), the cross-section intensity distribution of which has a predetermined shape. This technique is based on using multimodal Bessel beams. We can generate Bessellike non-diffracting beams by varying parameters of individual beams and adjusting their individual energy contribution to the generated light distribution. This technique allows designing transmission functions for elements that shape both non-rotating and rotating beams. Such laser beams can be used for controlled manipulation of non-spherical objects in liquids or air.
