00925njm 22002777a 4500 dc Rodrigo Martín-Romo, José Augusto author Alieva Krasheninnikova, Tatiana author 2015-08-01 We show that the propagation of the widely used Schell-model partially coherent light can be easily understood using the ambiguity function. This approach is especially beneficial for the analysis of the mutual intensity of Schell-model beams (SMBs), which are associated with stable coherent beams such as Laguerre-, Hermite-, and Ince-Gaussian. We study the evolution of the coherence singularities during the SMB propagation. It is demonstrated that the distance of singularity formation depends on the coherence degree of the input beam. Moreover, it is proved that the shape, position, and number of singularity curves in far field are defined by the associated coherent beam. 0146-9592 10.1364/OL.40.003635 https://hdl.handle.net/20.500.14352/24176 http://dx.doi.org/10.1364/OL.40.003635 https://www.osapublishing.org Evolution of coherence singularities of Schell-model beams
