Generalized tensor ABCD law for an elliptical Gaussian beam passing through an astigmatic optical system in turbulent atmosphere

Cai, Yangjian; Lin, Q.; Eyyuboğlu, Halil T.; Baykal, Yahya (Springer, 2009-02)

The propagation of an elliptical Gaussian beam (EGB) through an astigmatic ABCD optical system in a turbulent atmosphere is investigated. An analytical formula for the average intensity of an EGB and a generalized tensor ...
Scintillation of astigmatic dark hollow beams in weak atmospheric turbulence

Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2008-07)

The scintillation properties of astigmatic dark hollow beams (DHBs) in weak atmospheric turbulence were investigated in detail. An explicit expression for the on-axis scintillation index of an astigmatic DH13 propagating ...
