PICAS: Photonically Integrated Cold Atom Source

We present a compact optical delivery design for a 2D+ MOT used with a magnetic assembly and a commercial vacuum piece to create a standardised cold atom source. PICAS 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 that forms a multiply split cylindrical beam.

Progress towards a portable cold-atom pressure standard

All existing pressure standards (classical and quantum-based) are large apparatuses - typically, the size of a van or larger. In this thesis, we report on the progress towards building a portable version of a cold-atom based pressure standard which can easily transported by a van instead. Specifically, we discuss - the flexible laser design that can produce 780 nm pump light anywhere in a 26 GHz range and repump light anywhere in a +/- 6.8 GHz range within <1 MHz with no realignment. - the magnetic field coils that can produce gradients in excess of 400 G/cm without changing temperature (provided that >14 mL/s of 10 C to 15 C water is available. - the low-outgassing vacuum chamber that can supply rubidium for measurement while minimizing contamination in the chamber under test. - preliminary results characterizing the performance of its rubidium source and magneto-optical trap. - future plans for the apparatus. This pressure standard leverages the linear relationship between the pressure of a vacuum.
