Miniaturized active optical dipole trap system for compact quantum sensing applications

We have developed a miniaturized active optical dipole trap system incorporating a piezoelectric MEMS mirror for beam steering. This enables dynamic time-averaged potentials for efficient atom trapping and manipulation in compact atomic quantum sensing applications.
