    (Numerical simulations, color online) The propagation of normal deformed 2D Airy beams (α=0.02, r0=40 μm, s1d=0, s2d=0, m=0) with different initial angles θ: (a) θ=60°, (b) θ=90°, (c) θ=120°. From the 1st to the 3rd column are the beam profiles at z=0, 4, and 8 cm, respectively, and the last column shows side views of beam propagation up to 8 cm, where the white (Yd1) and green (Yd2) dashed curves are plotted by calculating Eqs. (3a) and (3b), respectively.
    (Numerical simulations, color online) Same as in Fig. 1 but with a vortex of a unit topological charge (m=1) imposed as in Eq. (1).
    (Numerical simulations, color online) Same as in Fig. 1 but with a vortex of two unit topological charges (m=2) imposed as in Eq. (1).
    (Color online) Transverse power flow of the 2D Airy beams carrying different topological charges at z=0.3 mm: (a) m=0, (b) m=1, (c) m=2. From the 1st to the 3rd column corresponds to different initial wing angles: θ=60°, θ=90°, and θ=120°, respectively.
    (Color online) Experimental setup for the generation and propagation of deformed vortex Airy beams. PC: personal computer; L: lens.
    (Color online) Experimental results showing the transverse intensity patterns captured at different propagation distances for deformed 2D vortex Airy beams with different initial angles between the two wings. From the 1st to the 3rd column are the beam profiles at z=0 cm, z=4 cm, and z=8 cm, respectively, and the last column shows the corresponding holograms of the beams with different conditions.
