摘要: The on-axis scintillation index for a circular dark hollow beam (DHB) propagating in weak turbulent atmosphere is formulated, and the properties of DHB are investigated detail. reduces to Gaussian beam, an annular flat-topped under certain conditions. It found that closely related parameters can be lower than at smaller waist sizes longer propagation lengths.
