Study The Effects of Atmospheric Turbulence on Propagation of Laser Beam


Two theoretical methods for the calculation of turbulence attenuation to laser beam are used, the Rytov's approximation and Andrews’s method. These calculations were performed for some important communication wavelengths of 0.86 μm ,1.55 μm,3.50μm and 10.6μm.The distance between the optical transmitter and receivers system of horizontal links was set to values ranging from (0 to 3000) m. We have taken into account the homogenous turbulence at low and high values for structure parameter of refractive index.
