  • Annular, cosh and cos Gaussian beams in strong turbulence 
    Eyyuboğlu, Halil T. (Springer, 2011-06)
    For the strong atmospheric turbulence regime, the asymptotic on-axis scintillation behavior of annular, cosh and cos Gaussian beams is theoretically derived and illustrated with numerical examples. It is observed from the ...
  • Area scintillations of Bessel Gaussian and modified Bessel Gaussian beams of zeroth order 
    Eyyuboğlu, Halil T. (Springer, 2010-01)
    As an extension of our previous study, the area scintillation aspects of Bessel Gaussian and modified Bessel Gaussian beams of zeroth order are investigated. The analysis is carried out on the basis of equal source sizes ...
  • 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 cos-Gaussian and annular beams 
    Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2007-01)
    Based on the generalized beam formulation, we derive the scintillation index and selectively evaluate it for cos-Gaussian and annular beams propagating in weak atmospheric turbulence. Dependence of the scintillation index ...
  • Scintillations of partially coherent Laguerre Gaussian beams 
    Yüceer, Mehmet; Eyyuboğlu, Halil T.; Lukin, I. P. (Springer, 2010-12)
    Scintillations of Laguerre-Gaussian (LG) beams for weak atmospheric turbulence conditions are derived for on-axis receiver positions by using Huygens-Fresnel (HF) method in semi-analytic fashion. Numerical evaluations ...
