Abstract
The analytical propagation equations for partially coherent four-petal Gaussian vortex beams propagating through uniaxial crystals orthogonal to the optical axis are derived, and the propagation properties are analyzed by numerical examples. The influence of beam order , topological charge M, the coherence length, and the ratio of refractive index on the normalized intensity distribution of partially coherent four-petal Gaussian vortex beams is discussed.
