Abstract
Estimates of the radius of coherence of a laser beam and the possible beam broadening in the atmospheric boundary layer under the effect of random inhomogeneities of the refractive index, determined from experimental data of remote acoustic sounding, are presented. The possibility of significant loss of coherence and marked broadening of the laser beam due to turbulence in nighttime conditions is noted.
