Cold Atom 2D MOT Beam Coupler
The MP-MOT-101-130.7-113.4 is a highly integrated beam coupler designed specifically for cold-atom 2D magneto-optical traps. It accepts three fibre-laser inputs provided by the user and internally forms a standard 2D⁺ MOT beam configuration without requiring complex optical alignment from the user. When used with the Infleqtion CASC cold-atom source, it delivers pre-cooled atom fluxes exceeding 1×10⁹ atoms/s, providing a stable, high-efficiency atomic beam source for cold-atom experiments, quantum sensing, and quantum computing platforms. The module mounts directly onto the CAMAPA Coil Assembly, enabling true plug-and-play integration that significantly reduces system construction effort and tuning time.
Product features:Alignment‑free design – ready for use upon installation;Available in rubidium (Rb) and caesium (Cs) wavelength versions;Designed specifically for the CASC cold‑atom source;Standard 2D⁺ MOT beam configuration;7 mm viewing window for convenient 2D MOT imaging;Optional integrated power‑monitoring photodiodes;Polarisation cleaning support;Direct integration with coil assembly for rapid cold‑atom system setup
