Abstract:

The use of multipass cells has provided increased sensitivity by providing increased path length and therefore increased SNR for precision electromagnetic sensing. We investigated three different multipass setups based on a Herriott cell, a roofed mirror, and a corner cube retroreflector. The Herriott cell promises the most potential for future use, but would still require rigorous analysis of the polarization rotation through the cell especially if we desire to increase the number of reflections that are utilized. The potential for utilization in the optically pumped magnetometer relies on resolving any effects on the measurement approach, which relies on detection of a nonlinear magneto-optical rotation of the polarization
