Radio Frequency Magneto-Optical Trapping of CaF with High Density

Loïc Anderegg, Benjamin L. Augenbraun, Eunmi Chae +7 more

We demonstrate significantly improved magneto-optical trapping of molecules using a very slow cryogenic beam source and either rf modulated or dc magnetic fields. The rf magneto-optical trap (MOT) confines 1.0(3)×10^{5} CaF molecules at a density of 7(3)×10^{6} cm^{-3}, which is an order of magnitude greater than previous molecular MOTs. Near Doppler-limited temperatures of 340(20) μK are attained. The achieved density enables future work to directly load optical tweezers and create optical arrays for quantum simulation.We demonstrate significantly improved magneto-optical trapping of molecules using a very slow cryogenic beam source and either rf modulated or dc magnetic fields.

Laser slowing of CaF molecules to near the capture velocity of a molecular MOT

Boerge Hemmerling, Eunmi Chae, Aakash Ravi +7 more

Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened 'white-light' slowing and observe approximately 6 x 10⁴ CaF molecules in a single pulse with velocities 10 ± 4 m s⁻¹. CaF is a candidate for collisional studies in the mK regime. This work represents a significant step towards magneto-optical trapping of CaF.

Abstract Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened ‘white-light’ slowing and observe approximately 6 × 10 4 CaF molecules in a single pulse with velocities 10 ± 4 m s −1 . CaF is a candidate for collisional studies in the mK regime. This work represents a significant step towards magneto-optical trapping of CaF.
