Abstract
Atom interferometers possess great potential as sensitive and stable acceleration and rotation sensors. Currently, the DoD is interested in leveraging atom interferometry research to improve inertial sensors and develop portable, compact devices based on atom interferometers with strategic-grade performance. Typical atom interferometers measure the acceleration or rotation signal with an on-resonance detection laser field, but these laser fields have inherent noise that degrades the signal-to-noise ratio. The laser noise in one quadrature of the field can be reduced below the so-called shot noise limit at the expense of the other quadrature. Fields with this property are called “squeezed fields.” Although lowering the noise in one quadrature increases noise in the other quadrature (due to Heisenberg’s uncertainty principle), the noise in the other quadrature can be made irrelevant by designing a detection scheme that does not use that quadrature. By reducing light-source noise, atom interferometer measurement precision can be increased. This thesis aims to establish the groundwork for creating squeezed light to be used for the detection of atoms in the ground or excited state of the NPS Atom Interferometry Laboratory atom interferometer.
