Optical Trapping of a Polyatomic Molecule in an -Type Parity Doublet State
Physical Review Letters, 2023•APS
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) μ K in free
space and loaded into an optical dipole trap. We attain an in-trap molecule number density
of 3 (1)× 10 9 cm-3 at a temperature of 57 (8) μ K. Trapped CaOH molecules are optically
pumped into an excited vibrational bending mode, whose ℓ-type parity doublet structure is a
potential resource for a wide range of proposed quantum science applications with …

Trapped CaOH molecules are optically pumped into an excited vibrational bending mode, whose -type parity doublet structure is a potential resource for a wide range of proposed quantum science applications with polyatomic molecules. We measure the spontaneous, radiative lifetime of this bending mode state to be .
