Towards optical cycling in calcium and strontium phenoxides
POSTER
Abstract
Laser-induced fluorescence measurements have demonstrated that chemical functionalization makes it possible to design polyatomic metal-oxide-radical (MOR) molecules possessing strong optical transitions with large diagonal branching ratios, indicating that with a high probability, they return to the original vibration state after a single optical excitation-emission cycle. This property makes them promising candidates for achieving optical cycling, an essential step towards laser cooling and trapping, with just a few lasers. Here, we present our approach toward achieving optical cycling in polyatomic MOR molecules, specifically CaOC6H5 and SrOC6H5, which have been previously produced and characterized in our lab. Using cryogenic buffer gas cooling and optical excitation with highly tunable continuous-wave dye lasers provides our experimental apparatus with the versatility to study various molecules and the possibility of an upgrade for laser cooling and quantum state preparation and measurements.
