Abstract

We report the experimental generation of a high-quality partially coherent dark hollow beam (DHB) by coupling a partially coherent beam into a multimode fiber (MMF) with a suitable incidence angle. The interference experiment of the generated partially coherent DHB passing through double slits is demonstrated. It is found that the coupling efficiency of the multimode fiber, the quality and the coherence of the generated partially coherent DHB are closely controlled by the coherence of the input beam. A partially coherent elliptical DHB is generated through focusing the generated partially coherent DHB with a cylindrical lens.
