2D Magneto-Optical Trap2D-MOT
Plug-and-play 2D MOT cold atom beam
A plug-and-play cold atom beam source with stable cold-atom beam flux exceeding 1×109 atoms/s (Rb / Cs). Internal optics are factory pre-aligned and fixed — no field alignment required. Ultra-compact and rugged, it's the ideal cold-atom front-end for portable quantum sensors and neutral-atom quantum computing platforms.
How It Works
From laser cooling and the magneto-optical trap to the cold atomic beam — the 2D-MOT explained (about 4 minutes, English narration).
Key Features
Built to be batch-deliverable — so you spend time on physics, not on building systems.
Ultra-High Flux
Stable cold-atom beam flux exceeding 1×109 atoms/s (Rb / Cs), dramatically shortening cold atom loading time in science chambers.
Fixed Optical Path
Internal optics are pre-aligned and fixed at the factory, eliminating time-consuming beam alignment.
Plug-and-Play
Connect the laser via fiber and power the coils to output a stable 2D cold atom beam; portable with the vacuum system.
Compact & Rugged
A fraction of the size of traditional table-top systems, with a rugged integrated build for long-term operation and transport with the vacuum system — ideal for portable quantum sensors and neutral-atom platforms.
Active Coil Design
Low power consumption and minimal coil heating for better thermal stability; gradient adjustable over 0–25 G/cm with fast switching for complex experimental timing sequences.
Multiple Atom Sources · Fast Swap
Up to 3 alkali metal dispensers in the source cell: mix Rb and Cs for dual-species operation, or fit several of one metal for longer service life. Modular design for quick replacement (requires venting, followed by pump-down and bakeout).
