Optical Trapping of a Polyatomic Molecule in an $\ell$-Type Parity Doublet State

Christian Hallas, Nathaniel B. Vilas, Loïc Anderegg +5

We report optical trapping of a polyatomic molecule, calcium monohydroxide (CaOH). CaOH molecules from a magneto-optical trap are sub-Doppler laser cooled to $20(3)\mu \text{K}$ in f…
