The effective radius of curvature of hyperbolic and sinusoidal Gaussian beams in free space and turbulent atmosphere is studied analytically and numerically. It is shown that the radius of curvature rises with growing ...
Analysis of flat-topped Gaussian vortex beam scintillation properties in atmospheric turbulence

Elmabruk, Kholoud; Eyyuboğlu, Halil T. (Spie-Soc Photo-Optical Instrumentation Engineers, 2019-06)

We analyze the scintillation properties of a flat-topped Gaussian vortex beam propagating in a weakly turbulent atmosphere. We utilize a random phase screen model to perform this analysis. We evaluate the scintillation ...
Analysis of laser multimode content on the angle-of-arrival fluctuations in free-space optics access systems

Eyyuboğlu, Halil T.; Baykal, Yahya (Spie-Soc Photo-Optical Instrumentation Engineers, 2005-05)

The effects of laser beam multimode content on the angle-of-arrival fluctuations are examined for free-space optics (FSO) access systems. Multimode excitation is represented by coherent addition of Hermite-Gaussian modes. ...
Analysis of reciprocity of cos-Gaussian and cosh-Gaussian laser beams in a turbulent atmosphere
