Abstract
A new kind of laser beam, named a decentered controllable elliptical dark-hollow beam (DCEDHB), is defined by a tensor method. The propagation formula for a DCEDHB through an axially nonsymmetrical optical system is derived by vector integration. The derived propagation formula could be reduced to the formula for a controllable elliptical dark-hollow beam (CEDHB) and a controllable dark-hollow beam (CDHB) under certain conditions. As an application example of the derived formula, the propagation characteristics of a DCEDHB in free space are calculated and discussed. As another example we study the propagation properties of coherent and incoherent beam combinations with radial array for DCEDHB.
