The purpose of this research effort is to experimentally generate an electromagnetic Gaussian Schell-model beam from two coherent linearly polarized plane waves. The approach uses a sequence of mutually correlated random phase screens on phase-only liquid crystal spatial light modulators at the source plane. The phase screens are generated using a published relationship between the screen parameters and the desired electromagnetic Gaussian Schell-model source parameters. The approach is verified by comparing the experimental results with published theory and numerical simulation results. This work enables the design of an electromagnetic Gaussian Schell-model source with prescribed coherence and polarization properties.
