? 2021 Elsevier B.V.In this paper, we established the relationship model between Rayleigh length of incident Gaussian beam and in-plane angular spin splitting (IPASS) under arbitrary linear polarization, and systematically investigated the effect of Rayleigh length on the IPASS. The results show that the IPASS shifts decrease with the increase of Rayleigh length, and the smaller the Rayleigh length, the greater its impact on IPASS. The maximum IPASS shift can almost reach half of the beam divergence angle by adjusting incident angle and polarization angle. In addition, several interesting characters of IPASS are discovered.
