Properties of off-axis caustics of autofocusing chirp beams

Abstract

Autofocusing properties of chirp beams with an arbitrary power-law dependence on the radius are studied theoretically and numerically. Two- and three-parameter chirp beams are considered, the parameter variations of which make it possible to effectively control their autofocusing properties. The results obtained have a potential for various applications in optics and photonics.
