Figures & Tables

Fig. 1. (Numerical simulations, color online) The propagation of normal deformed 2D Airy beams ( $α = 0.02$ , $r_{0} = 40 μm$ , $s_{1 d} = 0$ , $s_{2 d} = 0$ , $m = 0$ ) 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 ( $Y_{d 1}$ ) and green ( $Y_{d 2}$ ) dashed curves are plotted by calculating Eqs. (3a) and (3b), respectively.
