Abstract: | Absorption spectroscopy typically recovers the average thermodynamic properties along a laser path. However, broadband laser sources, including the dual frequency comb spectrometer, measure many absorption features which provide different temperature information about the path nonuniformity. We have developed a two-step approach to extract a nonuniform temperature distribution from a broadband absorption spectrum spanning hundreds of absorption features. We demonstrate how this approach resolves the path nonuniformity in a tube furnace as predicted by natural convection theory. |
