    Abstract

    Optical intensity distributions in the focal region play an important role in many optical systems. In this paper, the focal patterns of hyperbolic-cosh-Gaussian (HCG) beam in focal plane were investigated by changing amplitude. It was found that the focal patterns can be altered very considerably by changing the charge number of the amplitude,and some novel focal patterns appear, including multiple rhombus and multiple focal spots arry.
