This dissertation is focused on the determination of turbulent atmospheric transmission media properties. The concept of new method for turbulent attenuation designation is presented – the method of available power. This method comes from laser beam intensity profile analysis. The next point of this work is relative variance of optical intensity study. On the basis of experimental measurements relative variance of optical intensity is non-uniformly distributed in laser beam intensity profile. This non uniform distribution is subordinated to angular coefficient of intensity profile curve. Due to this information we can determine optimal laser beam shape to minimize influence of turbulent atmosphere.
