“…Different fabrication techniques for constructing vapour cells for alkali-metal atoms are being developed [88][89][90][91][92]. Particularly noteworthy are the nanometric thin cells developed at the Institute for Physical Research, Armenia; these cells have been used to study a wide range of fundamental physics [93][94][95][96][97][98][99] and have sensing applications [100][101][102][103]. The spectra of atoms confined to thin cells is modified with respect to bulk cells, with interactions of atoms with the walls and cavity effects being dominant.…”

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 vapours are ideal media for quantum-optics experiments as they combine: a large resonant optical depth; long coherence times; and well-understood atom-atom interactions. These features aid with the simplicity of both the experimental set up and the theoretical framework. The topic attracts much attention as these systems are ideal for studying both fundamental physics and has numerous applications, especially in sensing electromagnetic fields and quantum technology. This tutorial reviews the necessary theory to understand the Doppler broadened absorption spectroscopy of alkali-metal atoms, and explains the data taking and processing necessary to compare theory and experiment. The aim is to provide a gentle introduction to novice scientists starting their studies of the spectroscopy of thermal vapours whilst also calling attention to the application of these ideas in the contemporary literature. In addition, the work of expert practitioners in the field is highlighted, explaining the relevance of three extensively-used software packages that complement the presentation herein.
