Abstract

We present a compact optical delivery design for a 2D+ MOT which is used in conjunction with a magnetic assembly and a commercial vacuum piece to create a standardised cold atom source. The design provides a plug-and-play system, free of optical alignment, capable of producing an atomic flux of >1e9 atoms per second with <50mW of laser power. The dimensions of the system are 67mm x 67mm x 112mm (W x H x L), where such compactness is achieved through a fixed optical design, additive manufacturing techniques, and a novel beam expansion method which forms a multiply split cylindrical beam.
