摘要
The equations of anomalous hollow beam (AHB) in slant atmosphere have been derived, and the average intensity distributions have been illustrated and analyzed using numerical examples. The results shown that the AHB propagating in slant atmosphere will lose the initial dark hollow with a solid core profile and evolve into Gaussian beam as the propagation distance increases. The results also shown the AHB propagating in slant atmosphere with larger strength (larger C-0 or small zenith angle alpha) will lose the initial beam profile faster at the same propagation distance L.
