Efficient Loading of an Yb MOT on the 1S0 → 1P1 Transition

We demonstrate efficient loading of an Yb three-dimensional magneto-optical trap (3D MOT) on the 1S0 → 1P1 transition. The experiment employs a two-dimensional magneto-optical trap (2D MOT) as an efficient cold atom source. Through optimization of the 2D MOT, auxiliary Zeeman slower, and push beam parameters that govern atomic capture, we achieve an atomic loading rate of 5 × 106 atoms/s in the 3D MOT, with approximately ∼107 trapped atoms. Our experimental results confirm the successful transfer of a substantial number of atoms from the 2D region to the science chamber via the push beam, providing an experimental foundation for subsequent implementation of narrow-line MOT and two-color MOT.
