Abstract
We report on the implementation of metallic microtubes in a system of rubidium vapour at 230\,bar of argon buffer gas. The high buffer gas pressure leads to a widely pressure broadened linewidth of several nanometers, interpolating between the sharp atomic physics spectra and the band structure of solid state systems. Tube-like metallic waveguide structures have been inserted in the high pressure buffer gas system, allowing for an enhancement of the atom-light interaction over an optical guiding length in the tube of up to 1\,mm. The system holds promise for nonlinear optics experiments and the study of atom-light polariton condensation.
