  • Average intensity and spreading of an elegant Hermite-Gaussian beam in turbulent atmosphere 
    Yuan, Yangsheng; Cai, Yangjian; Qu, Jun; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2009-06-22)
    The propagation of an elegant Hermite-Gaussian beam (EHGB) in turbulent atmosphere is investigated. Analytical propagation formulae for the average intensity and effective beam size of an EHGB in turbulent atmosphere are ...
  • M-2-factor of coherent and partially coherent dark hollow beams propagating in turbulent atmosphere 
    Yuan, Yangsheng; Cai, Yangjian; Qu, Jun; Eyyuboğlu, Halil T.; Baykal, Yahya; Korotkova, Olga (Optical Society of America, 2009-09-28)
    Analytical formula is derived for the M-2-factor of coherent and partially coherent dark hollow beams (DHB) in turbulent atmosphere based on the extended Huygens-Fresnel integral and the second-order moments of the Wigner ...
  • Propagation factors of Hermite-Gaussian beams in turbulent atmosphere 
    Yuan, Yangsheng; Cai, Yangjian; Qu, Jun; Eyyuboğlu, Halil T.; Baykal, Yahya (Elsevier Science Ltd, 2010-11)
    Based on the extended Huygens-Fresnel integral and the second-order moments of the Wigner distribution function, an analytical formulae for the propagation factors (M-2-factors) of coherent and partially coherent one-dimensional ...
  • Scintillation index of a multi-Gaussian Schell-model beam in turbulent atmosphere 
    Yuan, Yangsheng; Liu, Xianlong; Wang, Fei; Chen, Yahong; Cai, Yangjian; Qu, Jun; Eyyuboğlu, Halil T. (Elsevier Science Bv, 2013-09-15)
    Multi-Gaussian Schell-model (MGSM) beam was introduced recently [Sahin and Korotkova, Opt. Lett. 37 (2012) 2970; Korotkova et al., J. Opt. Soc. Am. A 29 (2012) 2159]. In this paper, an explicit expression for the scintillation ...
