Abstract

The definition of the orbital angular momentum established for coherent beams is extended to partially coherent beams, expressed in terms of two elements of the beam matrix. This extension is justified by use of the Mercer expansion of partially coherent fields. General Gauss–Schell-model fields are considered, and the relation between the twist parameter and the orbital angular momentum is analyzed.
