  • Abstract
    The effect of the strength of turbulence on the intensity distribution in the focal plane of a focused laser beam is studied. The intensity in the focal region is found to be unaffected by the turbulence provided Cn2< 0.45 k0-2S-5/6F-1, where Cnis the index of the refraction structure constant, k0is the signal wavenumber, S is the initial cross section of the beam, and F is the focal length.
