Ideal non-diffracting beams require an infinite amount of energy for generation and therefore not physically realizable. In experiments only their approximations as the pseudo-nondiffracting beam can be obtained. Super-Gaussian-Bessel (SGB) beams as pseudo-nondiffracting beam having finite energy are physically realizable. The constant-axial-intensity SGB beams have good non-diffracting characteristics over a certain propagation distance

their central region of transverse intensity distribution keep their intensity and size constant. In this paper

it was proved that constant-axial-intensity SGB beams still maintain the non-diffracting characteristics in the range of medium intensity of atmospheric turbulence by means of numeric simulation. The propagation of constant-axial-intensity SGB beams are hardly affected by atmospheric turbulence
