Propagation of a collimated Gaussian light beam in a weakly turbulent medium
Abstract
It is demonstrated that diffraction can be considered as a perturbation of the refractive index for the propagation of a collimated Gaussian beam in a weakly turbulent medium. This perturbation is approximated as a power series in the reciprocal of the product of the squares of the wave number and the transverse dimension of the beam. The statistical properties of the intensity are examined, assuming that the refractive index is a Gaussian transverse random variable. The present results are found to disagree with Ishimaru's (1978).
