Comparing thermal and lasing atomic sources for precision inertial measurement
We compare the sensitivity of an interferometric measurement of gravity using a freely-falling, lasing atomic source to that achieved with a cold, thermal atomic source. We observe a higher fringe visibility with the lasing source, also the highest yet observed in such a configuration. We improve sensitivity by exploiting large momentum transfer beamsplitting (LMT), and discuss briefly the advantages of using a lasing atomic source for LMT. Most importantly, we measure no degradation of the...[Show more]
