摘要：

The equation of a Lorentz-correlated Schell-model beam (LCSMB) in a uniaxial crystal is derived, and the relation of spreading properties and coherence with delta $\delta $ and n e / n o ${n}_{e}/{n}_{o}$ are analyzed during propagation. The intensity of an LCSMB in the uniaxial crystal will evolve from Lorentz distribution into diamond distribution, and the LCSMB with smaller delta $\delta $ will evolve from Gaussian distribution into Lorentz distribution faster. The distribution of coherence of an LCSMB will lose the Lorentz distribution and become an elliptical distribution as z $z$ increases.
