FIG. 1. Optical layout of the science chamber in the horizontal plane. The Cs (Yb) imaging beam is combined with the Cs (Yb) MOT beam using a polarizing beam splitter (dichroic mirror) and then separated after the chamber and aligned onto a CCD camera. The Raman lattice beams used for DRSC are split using a polarizing beam splitter, with one arm retroreflected and the other arm dumped after the first pass. The ODT used for thermalization measurements is referred to as the “dimple trap” to distinguish it from the large-volume “reservoir trap” that is used for the preparation of Cs BEC.
