Fig. 1. Formation of the vortex Airy–Bessel wave packet.

Fig. 2. Experimental setup to generate and measure the vortex Airy–Bessel wave packet. AC, Auto-correlation; XC, Cross-correlation.

Fig. 3. Dispersion and diffraction effects of the glass rod on (a) a Gaussian pulse and (b) and (c) a ring beam. The duration of the Gaussian beam is the same as the main lobe duration of the Airy pulse. The size of the ring is the same as the first ring of the first-order Bessel beam. The initial ring beam (b) expands ∼2 after the glass rod (c).

Fig. 4. 3D measurements of the vortex Airy–Bessel wave pocket. The iso-intensity profiles (a) without and (d) with the glass rod. The sagittal intensity profiles (b) without and (e) with the glass. The transverse phase in the range of (−π,π) profiles (c) without and (f) with the glass rod.
