"A Magnetometer and Gradient Magnetometer Atom Interferometer"

Frank Narducci , Naval Research Laboratory
[Host: Cass Sackett]
We are currently developing atom interferometric techniques to measure magnetic fields and magnetic field gradients to high precision. In this talk, I will review the selection rules associated with driving the eleven Raman resonances in 85Rb atoms in an arbitrarily oriented magnetic field, and how to use polarization of the Raman fields to enhance or suppress desired transitions. I will then present the results of well-known “clock” transition interferometric measurements made in my laboratory in both the time domain and the frequency domain. I will then present and discuss similar measurements made on magnetically-sensitive transitions. The analogy between our measurement techniques and the famous Young’s double slit experiment will be highlighted. Finally, I will present the first measurements of interference from our gradient magnetometer.
