High Compression Blue-Detuned Magneto-Optical Trap of Polyatomic Molecules

Atomic Physics 2024-04-05 v1

Abstract

We demonstrate a blue-detuned magneto-optical trap (MOT) of a polyatomic molecule, calcium monohydroxide (CaOH). We identify a novel MOT frequency configuration that produces high spatial compression of the molecular cloud. This high compression MOT achieves a cloud radius of 59(5) μm59(5)~\mu\text{m} and a peak density of 8(2)×108 cm38(2) \times 10^8~\text{cm}^{-3}, the highest reported density for a molecular MOT to date. We compare our experimental studies of blue-detuned MOTs for CaOH and compare with Monte-Carlo simulations, finding good agreement.
