Calculation of average intensity via semi-analytic method

Eyyuboğlu, Halil T.; Sermutlu, Emre (Springer, 2010-03)

We present a semi-analytic approach to the solution of the quadruple Huygens-Fresnel integral which is used to calculate the average receiver intensity of a source beam after it has propagated in a turbulent atmosphere. ...
Convergence of general beams into Gaussian intensity profiles after propagation in turbulent atmosphere

Eyyuboğlu, Halil T.; Baykal, Yahya; Sermutlu, Emre (Elsevier Science, 2006-09)

It is shown that a general shaped laser beam will eventually approach a Gaussian average intensity profile after propagation in turbulent atmosphere. In our formulation, source field at the exit plane of the laser is taken ...
Intensity fluctuations in J-Bessel-Gaussian beams of all orders propagating in turbulent atmosphere

Eyyuboğlu, Halil T.; Sermutlu, Emre; Baykal, Yahya; Cai, Yangjian; Korotkova, Olga (Springer, 2008-11)

The scintillation index of a J (n) -Bessel-Gaussian beam of any order propagating in turbulent atmosphere is derived and numerically evaluated at transverse cross-sections with the aid of a specially designed triple integral ...
Scintillation advantages of lowest order Bessel-Gaussian beams

Eyyuboğlu, Halil T.; Baykal, Yahya; Sermutlu, Emre (Springer, 2008-08)

For a weak turbulence propagation environment, the scintillation index of the lowest order Bessel-Gaussian beams is formulated. Its triple and single integral versions are presented. Numerical evaluations show that at large ...
Scintillation index of modified Bessel-Gaussian beams propagating in turbulent media

Eyyuboğlu, Halil T.; Baykal, Yahya; Sermutlu, Emre; Korotkova, Olga; Cai, Yangjian (Optical Soc Amer, 2009-02)

The scintillation index is formulated for modified Bessel-Gaussian beams propagating in weakly turbulent media. Numerical calculations applied directly to the derived triple integral show that, for off-axis positions, the ...
