Abstract
Thermal defocusing of a laser beam limits its power that can be efficiently transmitted through the atmosphere. The focusing in conditions of thermal blooming can be considered effective if the minimum radius of the circle complete interception of radiation is less than the radius of the initial aperture of the radiation source. In this paper we give an estimation technique of the efficiency of focusing of combined laser beams.
