Magneto-optical trapping with complicated level structures and geometries

As interest grows in miniaturization of atomic physics packages, tetrahedral and tetrahedral-like MOTs have received renewed interest, in part because of the advent of nanofabricated diffraction gratings. The grating MOT takes a single, incident laser beam and uses a diffraction grating to produce at least three more beams necessary to form a tetrahedral-like MOT. This simplified setup may prove vital toward miniaturization efforts, such as simplified chip-scale MOTS with a large grating coupler and custom diffraction grating to produce the necessary beams. We investigate the effects of level structure and trapping geometry on MOT parameters.
