Abstract

In this work, a novel spiral Airy beam with ultra-long anti-diffraction propagation distance and spiral intensity distribution is generated and studied. Changing the vortex topology charges and circular Airy phase parameters can flexibly modulate the properties of the beam, such as beam size, spiral intensity shape, propagation direction, and anti-diffraction propagation distance. Such beam has the property of self-healing and can restore to the spiral pattern. An array of spiral Airy beams can also be generated, and the spiral patterns and propagation directions of each beam of the array can be manipulated. This beam can be utilized in various applications such as optical tweezers and laser processing for chiral structures.
