Abstract
In this thesis, I designed and built laser systems to cool, trap and image lithium-6 and potassium-40 atoms. I also constructed the vacuum system for the experiment and experimentally tested a new method to coat the chamber with a Titanium-Zirconium- Vanadium alloy that acts as a pump. The final apparatus will use a 2D Magneto- Optical Trap (MOT) as a source of cool potassium and a Zeeman slower as a source of cool lithium. The atoms will then be trapped and cooled together in a double-species 3D MOT. In the 3D MOT, we will perform photoassociation spectroscopy on the atoms to determine the Li-K molecular energies and collisional properties. Using this information, we can transfer weakly-bound Feshbach LiK molecules into their ground state. LiK has an electric dipole moment and will open the door to the study of novel materials with very long-range interactions. This new material might form a crystal, a superfluid with anisotropic order parameter or a supersolid.
