摘要：We propose a new kind of partially coherent beam with a nonconventional correlation function termed as Hermite-cos-Gaussian correlated Schell-model (HcGCSM) beam. The propagation properties of this novel model beam are investigated. It is found that the HcGCSM beam exhibits cascade self-splitting properties on propagation in free space, i.e., the initial single beam spot is proved to be successively split for two times during the whole propagation. Furthermore, we demonstrate that the cascade self-splitting phenomenon can be closely controlled through modulating the spectral degree of coherence of a HcGCSM beam in the source plane.
