Fixed 2D MOT Beam Delivery Module

The MP-MOT-67-67-112 employs a fixed internal optical design that integrates beam shaping, polarisation control, and beam arrangement required for a 2D magneto-optical trap into a compact mechanical structure. Users simply connect three FC/APC fibres meeting the power and polarisation requirements to obtain a stable 2D MOT beam configuration. When used with the CASC cold-atom source, the system delivers pre-cooled atom fluxes exceeding 10⁹ atoms/s. The module mounts directly onto a permanent-magnet assembly, significantly reducing the optical alignment, magnetic-field tuning, and long‑term maintenance traditionally associated with 2D MOT systems.
