Title A proposal for a new high - bandwidth, E.I.T.-enhanced Pump- Probe atomic magnetometer
Creator Katsoprinakis, Yiorgos
Abstract In recent years, atomic magnetometers have become competitive with the world stan- dard in magnetic ―eld measurements, the SQUIDs (Superconducting QUantum In- terference Devices), rivaling their unprecedented sensitivity and ―nding applications in diverse ―elds, ranging from medicine and geology to sensitive tests of potential violations of fundamental symmetries. In this thesis we present a variation of the pump-probe magnetometer ([1], [11]), in which the magnetic ―eld is measured via the paramagnetic Faraday rotation of the polarization plane of a linearly polarized probe laser beam passing through an optically pumped alkali vapor, subject to this magnetic ―eld. Whereas the sensitivity of such devices is excellent at DC to low fre- quency AC magnetic ―elds, it quickly deteriorates at higher frequencies. We propose creating EIT (Electromagnetically Induced Transparency) conditions for the probe beam, which results in an increase of the useful bandwidth of the magnetometer by a factor on the order of 10^2.
