Results of Acoustic Diagnostics of Atmospheric Boundary Layer in Estimation of the Turbulence Effect on Laser Beam Parameters

Abstract

The coherence length and possible broadening of a laser beam in the atmospheric boundary layer under the effect of random inhomogeneities of the refractive index are estimated from experimental data of remote acoustic sounding. The possibility of significant loss of coherence and noticeable broadening of the laser beam due to turbulence in nighttime are noted.
