摘要：

We introduce an efficient approach to simultaneously tailor the spatial profile and the degree of coherence (DOC) of par-tially coherent light by devising its statistical properties in the spatial frequency domain. The relationship between the beam profile and the DOC in the source plane and the corre-lation function and power spectrum in the spatial frequency domain is analyzed in detail. This approach enables us to generate partially coherent sources with spatially uniform or non-uniform coherence states, and the source profiles are controlled. The condition for switching two coherence states is given through two theoretical examples. Furthermore, we validate our approach in experiment through generating two kinds of spatially non-uniform correlated sources with con-trollable beam profiles. The experimental results agree well with our theoretical analysis. (c) 2023 Optica Publishing Group
