Paper Abstract

In conditions of high turbulence, propagation of laser radiation along the horizontal path is characterized by significant decrease of intensity in far zone. Due to different factors, opportunities of adaptive means for atmospheric compensation in this case are rather poor. The possible way for overcoming the turbulence is to elevate the output aperture of the laser optical system over the most perturbed atmospheric layers. As the performed calculations have shown, the elevation up to 15 meters allows us to increase the tolerated turbulence range almost eight-fold.
