Scintillation behavior of cos, cosh and annular Gaussian beams in non-Kolmogorov turbulence

Eyyuboğlu, Halil T. (Springer, 2012-08)

For a non-Kolmogorov spectrum, scintillation aspects of cos, cosh and annular Gaussian beams are investigated. The appropriate mathematical formulation is developed, the derived scintillation index is evaluated and its ...
Scintillation behavior of Laguerre Gaussian beams in strong turbulence

Eyyuboğlu, Halil T.; Baykal, Yahya; Falits, A. (Springer, 2011-09)

In strong atmospheric turbulence, the asymptotic on-axis scintillation behaviors of Laguerre Gaussian (LG) beams are examined. To arrive at the strong-turbulence solution, we utilize the existing filtering approach for ...
Scintillation index of flat-topped Gaussian laser beam in strongly turbulent medium

Gerçekçioğlu, Hamza; Baykal, Yahya (Optical Soc Amer, 2011-08)

In a strongly turbulent medium, the scintillation index of flat-topped Gaussian beams is derived and evaluated. In the formulation, unified solution of Rytov method is utilized. Our results correctly reduce to the existing ...
Scintillations of higher-order laser beams in non-Kolmogorov medium

Baykal, Yahya (Optical Soc Amer, 2014-04-01)

In an atmospheric medium that shows a non-Kolmogorov turbulence behavior, the variation of the on-axis scintillation index is evaluated when higher-order laser modes are used as the excitation. The Rytov method is employed ...
