Abstract

The objective of this project is to create an optical vector magnetometer. When completed, this device will use the EIT resonances of Rubidium vapor to create a three dimensional vector map of an unknown magnetic field. In this paper, we report on two important capabilities of such a device. First, we demonstrate its potential for magnetic field detection of non-transparent targets by retro-reflecting the probe laser back through our target cell. We observe that the electromagnetically induced transparency signals (EIT) change neither frequency nor shape when retro-reflected. Second, we report the direct measurement of both magnitude and direction of an applied magnetic field is possible. We accomplish this by measuring the magnetic field along two perpendicular directions. Each measurement direction yields a plane that contains the magnetic field vector, and we show that the magnetic field vector is the intersection of the two planes.
