Generation of spatiotemporal Airy-Bessel wave packets

We demonstrate both theoretically and experimentally diffraction-free propagation and self-accelerating properties of linear spatiotemporal Airy-Bessel wave packets. We show that these beams display two distinct profiles: zero-vorticity rings and vortex beams for zero and integer topological charges...

Description
Summary:We demonstrate both theoretically and experimentally diffraction-free propagation and self-accelerating properties of linear spatiotemporal Airy-Bessel wave packets. We show that these beams display two distinct profiles: zero-vorticity rings and vortex beams for zero and integer topological charges, respectively. The experimental observations agree with theoretical analysis very well.
