This thesis reports work extending the scope of a recently developed gas sensing technique, multi-mode absorption spectroscopy (MUMAS). The ability of MUMAS to simultaneously detect multiple species from a mixture is demonstrated for the first time. The technique is subsequently extended to mid-infrared wavelengths, realising large gains in sensitivity.
A solid-state, multi-mode laser has been developed to provide a high-performance comb source for use with MUMAS. This in-house cons...Expand abstract
