| Description | Journal: Chinese Physics B Ac-Stark shift of atom levels is caused by an ac-electromagnetic field. As an electromagnetic wave, laser light does induce ac-Stark shift. It is proved experimentally that if the light is linearly polarized, the dynamic polarizability changes with polarization direction. The polarization direction of the linearly-polarized laser is tuned by 720°, and the ac-Stark shifts of the $4S_{1/2,m = ±1/2}$ → $3D_{5/2, m = ±1/2}$ clock transitions in$ ^{40}Ca^{+}$ are measured in steps of 10°. The frequency shifts change with laser polarization in a periodical manner and have values opposite to each other. |
