Which outcome reduces the performance of free-space optical communication systems using lasers in the atmosphere?

💡 Explanation

Atmospheric turbulence causes variations to the index of refraction, resulting in beam spreading and phase front distortion from decreased spatial coherence. This is scintillation effects because wave interference creates intensity fluctuations, therefore reducing beam strength, rather than effects like excitation reduction.
