  • Active laser radar systems with stochastic electromagnetic beams in turbulent atmosphere 
    Cai, Yangjian; Korotkova, Olga; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2008-09-29)
    Propagation of stochastic electromagnetic beams through paraxial ABCD optical systems operating through turbulent atmosphere is investigated with the help of the ABCD matrices and the generalized Huygens-Fresnel integral. ...
  • Atmospheric Propagation Model and Affecting On Laser Beam Propagation Via Free Space 
    Khamees, Hussein T. (OSA - The Optical Society, 2017)
    In this article, a laser source (He-Ne) laser with maximum output power ( 2.95 mW) was used to study and analyze laser beam when the laser propagates through the atmosphere. Atmosphere layer, also the spot diameter of the ...
  • Cosine-Gaussian laser beam intensity in turbulent atmosphere 
    Eyyuboğlu, Halil T.; Baykal, Yahya (Spie-Int Soc Optical Engineering, 2004)
    The effects of turbulent atmosphere on cosine-Gaussian laser beams are examined. To this end, a cosine-Gaussian excitation is taken at the source plane, and subsequently the average intensity profile at the receiver plane ...
  • Propagation of cross beams through atmospheric turbulence 
    Yenice, Y. E.; Eyyuboğlu, Halil T.; Baykal, Yahya (Spie-Int Soc Optical Engineering, 2005)
    Propagation properties of cross beam in turbulent medium are studied. A cross beam is constructed by the sum of two highly asymmetric Gaussian beams placed along transverse axes. It is known that such beams, when propagating ...
  • Receiver-aperture averaging of annular beams propagating through turbulent atmosphere 
    Kamacıoğlu, Canan; Baykal, Yahya; Yazgan, Erdem (Spie-Soc Photo-Optical Instrumentation Engineers, 2013-12)
    For an annular beam incidence, the power scintillation index in a weakly turbulent atmosphere is derived at the receiver plane, which has a Gaussian aperture. Employing this derivation, the receiver-aperture averaging ...
