TAS - Transmission spectra with Atom-Surface interactions

A Python package for generating transmission spectra through optically thin slabs of atomic vapours contained in spectroscopic cells of thickness < λ/(2π), where atom-surface van der Waals interaction induces level shifts. Generated spectra can be used for fitting results of atom-vapour laser spectroscopy to obtain strength of atom-surface interactions.

For more details on problem statement, solution method, assumptions and general use of package see documentation.

For example of use of generated spectra to obtain van der Waals interaction coefficient between alkali atoms and sapphire surface, see paper. Example of using data from paper and fitting procedure to obtain van der Waals interaction coefficient is provided in example notebook that can be run in browser using Binder.
