| contents | We have studied experimentally and theoretically the impact of various parameters on the characteristics of signals from a two-axis Hanle magnetometer based on the Cs D$_1$ transition illuminated by linearly polarized pump and probe beams propagating through the cell in such a way that the probe polarization vector can be switched between the $zy$- and the $xz$-plane in order to measure the magnetic field along the $x$- and $y$-axes, respectively. When the probe polarization additionally is reflected about the pump polarization vector and the two resulting absorption signals are subtracted, dispersion signals centered around zero are obtained. These dispersion signals can be reproduced accurately by the theoretical model, and the information from experiment and modeling used to optimize the magnetometer characteristics. |
