Abstract: (4631 Views)
Beam propagation factor of flat-topped (FT) beam through atmospheric turbulence is investigated based on the extended Huygens–Fresnel integral and the Wigner distribution function. Our results show that beam quality of FT beam in turbulence depends on the beam characteristic, for example order of FT beam, degree of spatial coherence length and also model of optical turbulence and its parameters. Moreover, the effect of the turbulence on the beam quality of FT beam is smaller for beam with a higher order and a lower degree of spatial coherence length of the source.
