| Abstract: | The probability distribution of the beam-centre wanders and the probabilitydistribution of the fluctuating average intensity measured by the point-aperture and causedby beam wander have been studied by using the probability theroy for laser beampropagation in a turbulent atmosphere. The resultS shown, the probability distribution ofthe two-dimension beam wandrs obeys Rician distribution, and the probability distributionof the average intensity fluctuations measured by the point-aperture satisfies Gammadistribution. |
