It has been shown theoretically and experimentally that, in the case of extended ground paths under conditions of strong intensity fluctuations when the atmospheric-turbulence-structure parameter is determined based on the half-width of the mean diffraction picture in the lens focal plane, one should take into account the beam-diffraction parameters and laser-source spatial coherence.
