摘要：
The partially coherent elegant Laguerre-Gaussian (ELG) beam is of importance and exhibits extraordinary characteristics in many fields, such as optical communications and optical trapping. Here, we show a method to measure the topological charge of a partially coherent ELG beam. We find that the number of ring dislocations in the far-field complex degree of coherence is equal to the topological charge vertical bar l vertical bar of a partially coherent ELG beam. and which is confirmed experimentally. Our results will be useful for applications using partially coherent ELG beams. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
