Effects of turbulence on a Gaussian beam. Beam with \(w_0 = 1\) mm and \(\lambda = 1550\) nm propagated for 800 m for low (1st row), moderate (2nd row), and strong (3rd row) turbulence regime. The 1st column corresponds to the beam power density, the 2nd to the phase front, and the 3rd to the spatial coherence. The dashed circles correspond to the theoretical Fried parameter \(r_0\).
