Various fundamental-physics experiments such as measurement of the magnetic
birefringence of the vacuum, searches for ultralight dark-matter particles (eg, axions), and …

The spectroscopy of hot atomic vapours is a hot topic. Many of the work-horse techniques of
contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic …

State-of-the-art magnetic field measurements performed in shielded environments under
carefully controlled conditions rarely reflect the realities of those applications envisioned in …

Transitions between the extreme angular-momentum states of alkali D lines hold the
potential for enabling accurate high-field optical magnetometry because of their very simple …

This paper provides details of a spectroscopic investigation of a thermal 87 Rb atomic
vapour. The experiment was conducted with an external magnetic field of 1.5 T in the Voigt …

The Laboratoire National des Champs Magnétiques Intenses (LNCMI) is a French host
facility for experiments in high magnetic fields. Based on two sites, the LNCMI offers …

We present a novel high-field optical quantum magnetometer based on saturated absorption
spectroscopy on the extreme angular-momentum states of the cesium D 2 line. With key …

We observe electromagnetically induced transparency (EIT) in a V-system in a thermal
rubidium-87 vapour in the hyperfine Paschen-Back regime, realised with a 0.6 T axial …

Measurements of electron paramagnetic resonance (EPR) close to the saturation region of
iron-core electromagnets (ca. 1 Tesla) require precise magnetic field calibration due to …

Cascading light through two thermal vapour cells has been shown to improve the
performance of atomic filters that aim to maximise peak transmission over a minimised …
