研究目的
To design, construct, and operate a versatile dual-species Zeeman slower for both Cs and Yb, adaptable for use with other alkali metals and alkaline earths, and to demonstrate efficient loading of MOTs with these atoms.
研究成果
The dual-species Zeeman slower efficiently loads more than 10^9 Yb atoms and 10^8 Cs atoms into their respective MOTs within a few seconds, providing an ideal starting point for further experiments on ultracold mixtures and molecules.
研究不足
The performance of the slower is affected by real-world issues such as fluctuations in laser intensity, magnetic field profile, and atom beam collimation. The design requires careful optimization to minimize these effects.
1：Experimental Design and Method Selection:
The design involves a Zeeman slower for both Cs and Yb, utilizing specific atomic transitions for each species. The method includes analytic models and numerical simulations to optimize the slower's performance.
2：Sample Selection and Data Sources:
Cs and Yb atoms are used, effusing from an oven with a vapor pressure around 10^-3 mbar.
3：List of Experimental Equipment and Materials:
Includes a Zeeman slower, atomic ovens, laser systems for 399 nm and 556 nm transitions for Yb, and 852 nm for Cs, and magnetic field coils.
4：Experimental Procedures and Operational Workflow:
Atoms are slowed and captured into MOTs using the Zeeman slower, with the ability to switch between loading Yb or Cs in under 0.1 s.
5：1 s.
Data Analysis Methods:
5. Data Analysis Methods: Performance is evaluated based on the number of atoms loaded into the MOTs and the efficiency of the slowing process.
