Simulations of beam transverse intensity patterns of three-Airy autofocusing beam carrying L = 7 vortex with initial wing angle θ = 75° (a), 90° (b), and 110° (c) at propagation positions z = 3 mm (a1), 14 mm (a2), 19 mm (a3), 2 mm (b1), 11 mm (b2), 15 mm (b3), 1 mm (c1), 8 mm (c2), and 12 mm (c3). Right three columns and central insets are for corresponding experimental results and phase mask.
