Abstract

We are developing a micro-fabricated platform to support the creation of laser cooled samples for chip scale instruments. Our chip scale cell is 4 mm thick and 28mm × 28mm wide, is made by anodically bonding glass windows to a silicon frame and is pumped by a 2 L/sec ion pump. Six independent laser beams, each having 1mW power, and a pair anti-Helmholtz coils are used to cool and trap ~ 5×10⁵ atoms. We have characterized the MOT system and we are in the process of replacing the actively pumped cell by a passively pumped cell where the pumping elements are non-evaporable getters.
