Abstract
SynopsisIn this work, we present how the AC-Stark shift can be suppressed by using twisted light beams for photoexcitations. Twisted light beams carry a non-zero projection of orbital angular momentum (OAM) onto their propagation direction, have a helical phase front and an intensity minimum in the beam center. Atoms located in this minimum experience a reduced AC-Stark shift and, therefore, twisted beams may be considered as valuable tool to drive atomic clock transitions. In this contribution, particular emphasis is paid to the electric-octupole (E3) transition 2 S1/2 → 2 F7/2 in the 171 Yb+ ion.
