Paper Abstract

The work is dedicated to study of turbulent distortions of focused laser beams propagating along high-altitude paths when both source and target are located at certain height in the middle atmosphere. The analysis was carried out for the model of refractive index spatial spectrum providing for anisotropy of turbulence, because there are anisotropic inhomogeneities of large sizes in the shape of disks extended along the Earth's surface in the stratosphere. A long exposure mean intensity distribution as well as a random wandering of laser beam are investigated depending on turbulence and geometry of propagation in the middle atmosphere. It is shown that the large anisotropic inhomogeneties of refractive index give the major contribution into vertical random wandering of a beam. As a result a long exposure distribution of mean intensity becomes anisotropic.
