摘要：
Starting from the propagation equation of partially coherent light, the spectral switching of Gaussian-Schell model (GSM) beams passing through an aperture lens is studied. Our detailed theoretical and numerical results have shown that the spectral switching of GSM beams is mainly dependent on the truncation parameter, coherence parameter and Fresnel number. By a suitable choice of the system parameters, the position, number, and transition amplitude of the spectral switch can be varied.
