Applied Physisc B-Lasers And Optics, 90(1), 87-92. http://dx.doi.org/10.1007/s00340-007-2825-10946-21711432-0649https://doi.org/10.1007/s00340-007-2825-1https://hdl.handle.net/123456789/11832The on-axis scintillation index for a circular dark hollow beam (DHB) propagating in a weak turbulent atmosphere is formulated, and the scintillation properties of a DHB are investigated in detail. The scintillation index for a DHB reduces to the scintillation index for a Gaussian beam, an annular beam and a flat-topped beam under certain conditions. It is found that the scintillation index of a DHB is closely related to the beam parameters and can be lower than that of a Gaussian beam, an annular beam and a flat-topped beam in a weak turbulent atmosphere at smaller waist sizes and longer propagation lengths.eninfo:eu-repo/semantics/closedAccessArticle10.1007/s00340-007-2825-12-s2.0-37449017251
