A Compact Cold Atom Gravimeter Utilizing a Grating Magneto Optical Trap

For a wide range of applications quantum gravimeters demands miniaturizing the physics package of a sensor which is, in laboratory environments, as big as a few meters. One approach to this end is adopting unconventional magneto-optical traps (MOT) such as pyramid MOTs [1] and grating MOTs (gMOT) [2]. In particular, grating MOT has opened an interesting opportunity to integrate complex experimental apparatuses into a planar chip [3], [4].
