Query: In Situ Characterisation of an Optically Thick Atom-Filled Cavity   A means for precise experimental characterization of the dielectric
susceptibility of an atomic gas inside and optical cavity is important for
design and operation of quantum light matter interfaces, particularly in the
context of quantum information processing. Here we present a numerically
optimised theoretical model to predict the spectral response of an atom-filled
cavity, accounting for both homogeneous and inhomogeneous broadening at high
optical densities. We investigate the regime where the two broadening
mechanisms are of similar magnitude, which makes the use of common
approximations invalid. Our model agrees with an experimental implementation
with warm caesium vapour in a ring cavity. From the cavity response, we are
able to extract important experimental parameters, for instance the ground
state populations, total number density and the magnitudes of both homogeneous
and inhomogeneous broadening.
