This paper provides details of a spectroscopic investigation of a thermal 87Rb atomic vapour. The experiment was conducted with an external magnetic field of 1.5 T in the Voigt geometry. Very good quantitative agreement between experimental data and theory is found for all four Stokes parameters—with RMS errors of ∼1.5% in all cases. From the fits to our experimental data a value for the magnetic field strength is extracted, along with the angle between the magnetic field and the polarisation of the light. The effects of the cell window birefringence on the optical rotation signals are characterised. This allows us to carry out precise measurements at a high field strength and arbitrary geometries, allowing further development of possible areas of application for atomic magnetometers.

“…The signal channel consists of a 1mm long isotopically enriched (99% 87 Rb) vapour cell, as used in [47], which is heated to provide the required atomic density and hence optical depth. Fabrication details of the vapour cell can be found in [59] and details of the isotopic purity and spectral qualities can be found in [60]. Both arms are mounted on a central bed of copper which also includes an internal heater, and a commercially calibrated magnetic-fieldinsensitive Cernox resistance thermometer (CX-1070-SD-HT-4M) [61] that is <5 mm from the vapour cell.…”

We present a detailed spectroscopic investigation of a thermal 87 Rb atomic vapour in magnetic fields up to 0.4 T in the Voigt geometry. We fit experimental spectra with our theoretical model ElecSus and find excellent quantitative agreement, with RMS errors of ∼ 0.3%. We extract the magnetic field strength and the angle between the polarisation of the light and the magnetic field from the atomic signal and find excellent agreement to within ∼ 1% with a commercial Hall probe. Finally, we present an investigation of the relative sensitivity of this technique to variations in the field strength and angle with a view to enabling atom-based high-field vector magnetometry.
