Abstract
AbstractThe possible laser cooling of AuAl molecules was investigated using high‐level ab initio calculations and considering the spin‐orbit coupling effect. Multi‐reference configuration interaction and the Davidson correction were also employed. Six Λ‐S electronic states were obtained, which were divided into 14 Ω states via spin‐orbit coupling. The optical transition showed potential for laser‐cooling applications owing to its highly diagonal Franck‐Condon factors and larger vibrational branching ratios. A possible optical cycling scheme using four lasers at near‐resonance wavelengths to eliminate vibrational branching loss is proposed. This scheme can be experimentally tested in future laser‐cooling experiments.
