Abstract: We put forward a powerful technique that allows generatingquasi-non-diffracting light beams with a variety of complex transverse shapesand topologies. We show that, e.g., spiraling patterns, patterns featuringcurved or bent bright stripes, or patterns featuring arbitrary combinations ofharmonic, Bessel, Mathieu and parabolic beams occupying different domains inthe transverse plane can be produced. The quasi-non-diffracting patterns openup a wealth of opportunities for the manipulation of matter and optical waves,colloidal and living particles, with applications in biophysics, and quantum,nonlinear and atom optics.
