Phase response of atom interferometers based on sequential Bragg diffractions

Year: 2018

Type: article

Abstract: Large momentum transfer (LMT) beam splitters are implemented in atom interferometers to increase their sensitivity. However, an LMT interferometer requires additional light pulses to modify the response function of the atom interferometer. In this paper, we develop an analytical model for the sensitivity function of LMT interferometers using sequential accelerating light pulses. We use the sensitivity function to calculate the acceleration sensitivity taking into account the pulse duration. In addition, the sensitivity to laser phase fluctuations is calculated, and we show that the pulse sequence can be engineered to mitigate the phase noise sensitivity.
