In the present communication, the propagation characteristics of structured beams are experimentally investigated using the two types of atmospheric turbulence simulators. These structured beams are defined by encoding the multiple phase singularities of topological l= 2 at the predefined locations in a plane wavefront. To generate these beams, the computer simulated holograms are displayed on the phase-only spatial light modulator which is illuminated by the collimated laser beam. The effect of atmosphere like turbulence is induced in the beams by the two turbulence simulators of strengths, i.e. D/r0 = 3.6 and 7.27 mm. The propagation performance parameters of these beams are estimated by analyzing the laser spot and the scintillation index. © 2019 Author(s).
