摘要：

Applications of laser beams to wireless communications are limited by the light intensity fluctuation caused by atmospheric turbulence when they propagate the atmosphere. In order to find out an approach to remove or decrease the effect of atmospheric turbulence on the beam quality, the axial and transverse light intensity distribution of the Super-Gaussian-Bessel (SGB) beam is investigated by means of a numeric simulation based on the general Huygens-Fresnel principle. As the SGB beam is characterized by its non-diffracting and self-reconstruction abilities over a certain propagation distance, it is proved that the axial intensity of the SGB beam is decreased under the influence of atmospheric turbulence, but its non-diffraction characteristics are still maintained over a certain propagation distance in the weak fluctuation. The peak intensity variation of the transverse intensity distribution of the SGB beam can be kept below 10 percent by selecting a proper aperture function in the range of weak fluctuation. These results show that the SGB beam has the ability to resist the influence of atmospheric turbulence.
