Paper Abstract

Due to influence of atmosphere turbulence, distribution characteristics of laser speckles vary with propagation distances. In this paper, numerical calculation using a multiple-phase screen method is performed to simulate the propagation of laser beam in the turbulence. The distributions of intensity at different distances are calculated. A characteristic factor σ 2 is proposed to quantify the degree of turbulence induced intensity spatial fluctuation compared with the same beam propagating in vacuum. The results show that, at the same distance, mean σ 2 of the beam propagating perpendicularly is smaller than the beam propagating horizontally. For a perpendicularly transmitted Gaussian beam, mean σ 2 decreases gradually after it reaches its maximum value, and tends to be stable if the propagation distance is long enough.
