We present the polarization‐ and orientation‐dependent characteristics of the differential light shifts (DLSs) in 87 Rb using the near‐resonant, stimulated Raman spectroscopy with an atomic fountain clock. Simulation and experimental results demonstrate that the Raman resonant frequencies would shift sinusoidally as the rotation of the laser's polarization vector due to the polarization‐dependent vector and tensor DLSs, and the total DLS is counteracted in some elliptically polarized laser configurations. What is more, this paper provides an alternative method to measure the effective magnetic field vector and the absolute scalar, vector, and tensor (SVT) DLSs and to verify the theoretically calculated SVT dynamical polarizabilities. These results will facilitate the evaluation and elimination of the light shift‐related systemic errors in the atomic optics‐based quantum sensors, including the atomic magnetometer, atomic interferometer, atomic clock, and quantum register.
