$\Lambda$-Enhanced Imaging of Molecules in an Optical Trap

Atomic Physics 2018-08-29 v1 Quantum Gases

Abstract

We report non-destructive imaging of optically trapped calcium monofluoride (CaF) molecules using in-situ Λ\Lambda-enhanced gray molasses cooling. 200200 times more fluorescence is obtained compared to destructive on-resonance imaging, and the trapped molecules remain at a temperature of 20μK20\,\mu\text{K}. The achieved number of scattered photons makes possible non-destructive single-shot detection of single molecules with high fidelity.
