The propagation of a partially coherent rectangular flat-topped laser array in a turbulent atmosphere is studied. An analytical expression for the average intensity distribution at the receiving plane is obtained based on an extended Huygens–Fresnel principle. The effect of correlation length, intensity of turbulence, laser numbers, and beam orders on the beam quality in a target plane is studied by numerical examples.
