Strong Amplitude Fluctuations of Wave Fields Propagating through Turbulent Media

摘要

A fundamental problem in laser-beam propagation through air is to determine the statistics of the fluctuating irradiance. To date this problem is still unsolved in the strong-optics regime (where scintillation is appreciable). This work presents an exhaustive survey, correction, and expansion of the results that can be obtained through selective summation of averaged products of Born-series terms substituted for the electric field in the average field, the mutual-coherence factor, and the N-th moment of the irradiance. Detailed error analyses and regimes of validity are provided. (Author)
