Abstract
A high bandwidth gravimeter or accelerometer includes laser(s), modulator(s), and an atomic interferometer. The laser(s) and modulator(s) produce four laser frequencies. A first and second pair of laser frequencies are each separated by w. The first and second pair are offset by w. A first laser frequency of the first pair and a second laser frequency of the second pair are separated by w+w. A second laser frequency of the first pair and a first laser frequency of the second pair are separated by w−w. The first pair is routed to arrive from a first direction at atoms in an interaction region, and the second pair from a second direction. The first pair are phase stable with respect to the second pair. wis adjusted so that w+wor w−wcorresponds to a Raman resonance for the atomic interferometer.
