摘　　要：We investigate a family of radially polarized Pearcey–Gauss vortex beams(RPPGVBs),obtain the general propagation expressions of an RPPGVB,and study the intensity distribution,phase pattern,spin currents as well as the orbital currents when the RPPGVB propagates in free space.The focal plane and the intensity of the focal point can be adjusted by changing the position of the vortex and the scaling factors.We also investigate how the waist size influences the propagation properties.
